Edited to add: The artist who drew this, Plognark, left a comment below, which totally rawks. If you like this cartoon -- and you should -- then read his stuff, and buy the t shirt.
You know, I try to be polite here. Sure, I'll call 'em like I see 'em, but I try to avoid the ad hominems and such. But still, I'm thinking a drawing like this will come in handy sometimes. No matter how patient you are, there comes a time when you need to get something like this off your chest.
Hat tip to a random thread on Fark, from which many such ideas flow.
