Lola: Where's my warming, Al Gore?

This comic is hilarious because Lola does not understand how global warming works.

Garfield: I finally nailed it back down!

This Garfield, as usual, would be better without Garfield. But even with Garfield, it's pretty good, mostly because it manages a degree of subtlety that Paws Inc. rarely attempts. The funny part of the comic is Jon's bandaged hand. Garfield's cheap punchline is mostly just a distraction.

Family Circus: Could I have one for Billy, one for Dolly, and one for PJ?

Clearly, Jeffy is a fucking idiot. But it seems to me that it would behoove Thel to look beyond her son's glaring stupidity and see that he has, for once, done something rather thoughtful in requesting lollipops for his siblings.

Sadly, Thel is most likely incapable of doing such a thing and, already seething with rage, will probably commence with Jeffy's beating as soon they get out the door.

Ziggy: ...You bought an off-brand, didn't you?

While Ziggy will probably let his bird continue thinking that out of shame, the reality is most likely far more disturbing.

Pluggers: Come to think of it, some things weren't better in the good ol' days.

I'm pretty sure that this is the sort of thing that gets your face plastered all over the telephone poles in Pluggerville.

Anne Jones of Arlington, Texas should probably be watching her back, as well.

Mark Trail: Oh, I forgot, I caught MORE fish than Mark!

Ha ha! Yes, that is definitely the lesson a human being would take from that series of events! You keep it up, Alien-Robot-Rusty thing! Those pathetic humans will never suspect a thing!

Archie and Garfield: 44usa

These stamps are hilarious because they feature characters from comic strips.

In all seriousness, both Archie and Garfield have made substantial marks on popular culture and deserve whatever enshrinement they get. So congratulations to Jim Davis and all the folks who have been involved with the various Archie series over the years.

All that said, the Internet indicates that the last time the Post Office put out stamps with comic strips on them was 1995, in their Comic Strip Classics collection, which was limited to strips that debuted before 1950. Pogo, which debuted in 1941 and was therefore eligible, was for some reason nevertheless not included. And it has now been displaced by Garfield. Which, again, is not to say that Garfield doesn't deserve to be honored for its immense commercial success and all the fans it has brought to the comics section. But Pogo has a legitimate claim to being the greatest comic strip ever produced. Something's amiss here.

UPDATE: As Jaime Weinman notes in the comments, Calvin and Hobbes, Beetle Bailey and Dennis the Menace are all getting honored with commemorative stamps this year as well.* Still no Pogo, though.

Calvin is obviously very deserving, and though it might not be so obvious now, so is Dennis, both for its cultural impact and for Hank Ketcham's artwork. I concur with Jaime that Beetle Bailey is less deserving, though I don't really think it's any less deserving than Garfield is. Jim Davis has done more with various corporate tie-ins, but Mort Walker probably deserves some sort of recognition for all the popular comics he's created over the years and that, for better or worse, continue to fill up the comics section to this day. There are other comics, even other than Pogo, that I would have chosen in their place, but I can't necessarily complain about either of them receiving an honor.

It's probably also worth mentioning that Bill Mauldin is getting a stamp, too. Beetle Bailey doesn't hold up very well when compared to something like this.

*How I managed to spend half an hour scouring the Internet for prior instances of comic strip stamps without learning this information I have no idea.

Family Circus: I forgot to give this to you and Daddy. I made it at school before Christmas.

This cartoon is hilarious because Billy really doesn't like his parents very much. And who could blame him?

F Minus: I wonder what cats think about.

This F Minus is basically the opposite of every comic strip or cartoon or book or movie about animals ever, which are always about how animals are Just Like Us. And that's why it's funny. It subverts our expectations.

It's also funny because it's true. Animals are not, in fact, Just Like Us.

Family Circus: ...

It appears that Dolly's attempt to control the natural environment has been thus far unsuccessful.
