Here's a cute little heartbreaker of an illustration that rarely fails to elicit a sympathetic "awwww" from the people I show it to. Mostly the women. A guy "awwwed" once and three other guys standing nearby beat him up. It was crazy.
Tell you what...that monkey party does look like fun. But that one little monkey is just too sad to enjoy it. I guess he misses his monkey girlfriend. Maybe it's his monkey ex-girlfriend. It's been such a long, lonely time since he had anyone special to throw poop at. Sigh. Wonder why they broke up?
Anyway, this was a gentler take on an earlier gag of mine where two guys were staring down into a barrel, one of them saying, "I guess it's a lot more fun if the monkeys are still alive." I was probably in a bad mood that day. Regardless, the whole thing got me thinking, once again, about the origin of the phrase. Luckily for me, the internet lives in the same machine where I do all my art. So I typed in the question and the answer was about what you'd expect. Read all about it here.
And when you're done engaging in illicit etymology, you can take a look at my work-in-progress steps below. Have fun. In fact, have a whole barrel of it. -v
