When I saw the comic below (many moons ago now), I burst out laughing.
Funny thing is, it was posted on a decidedly non-vegan site whose author used this to illustrate the folly and error of vegan ways. Kinda backfired methinks, because when you show the absurdity of one concept (quick rule of thumb for the "but plants have feelings too!" folk -- if a carrot doesn't scream when you lop its top off, it likely can't feel pain), it can actually strengthen the argument for another. In this case, the idea of showing solidarity for farmed animals in the many animal walks now common in numerous cities and countries. Not quite sure if the illustrator was also trying to poke fun at us, but hey, we should all (vegans and non-vegans alike) be able to see the humour in whatever it is that we do. The stereotype though, that vegans are unable to do this, is one that's gotta go. Plus it's one of the cop-out ways to try and discredit a group or movement. Cuz you know, all those feminists don't have a sense of humour either. Or anyone who doesn't laugh at a rape joke. Humour can be a double-edged sword: used wisely it can educate while entertain, cutting through bullshit in mere seconds, but sadly can also be used to keep tired myths and progressive groups in place.
Something else that made me laugh a while back even though it maybe wasn't supposed to, was a comment made by a character on Coronation Street, the world's longest-running TV soap and one of the few shows I won't have interrupted. I can't quite remember the context (although I believe it was Kylie talking about food allergies), and I'm paraphrasing here, but basically the line went something like this: Some people can't eat cows, some can't eat pork, others can't eat shellfish, and don't even get me started on vegans. I'm not sure why this prompted a loud guffaw on my part, but I suspect it was the unexpected -- hearing the word "vegan" on a television show, even in a derogatory way, is still novel enough that it pleases me enormously. Veganism has become mainstream enough to be made fun of (remember that humour can be a defense mechanism and non-vegans have a lot to be defensive about), so like it or not, vegan jokes are here to stay. Until of course the tipping point is reached and what is currently considered a minority stance becomes a majority one. But until then, let 'em laugh, because you know the old saying, she who laughs last... ;)
