So this joke is about as old as dirt, but I just recently had a debate with a friend of mine over what the joke actually means
So when you first heard the joke what meaning did you take from it? Sexual? Non-Sexual? What?
Please help end the argument.
Yes, sexual. Cannibalism is never funny.
I take it as performing cunnilingus on a young girl scout. It wouldn’t be funny otherwise.
Sexual
Heard it about forth grade.
the other one I heard (in 8th grade, I think) is:
Q: What’s blue and comes in Brownies?
A: Cub scouts.
I was kicked out of the Cub Scouts for hailing a water taxi. (Well, more than that, really, but it was the final straw.)
Cannibalism.
“This clown tastes funny.”
I assumed the punchline was sexual when I first heard it, but actually the non-sexual interpretation is funnier.
I heard it as
When does a Cub Scout become a Boy Scout?
When he eats his first Brownie.
The cannibal interpretation never occurred to me until I read the OP.
But the non-sexual interpretation doesn’t work without the sexual connotation.
“Eating a brownie,” if referring to masticating a chocolate confection, isn’t funny unless you equate it with cunnilingus on a young female scout.
Why would someone be penalized for munching on a cookie?
And as far as cannibalism goes, I guess that works as humor for 4th graders, but elephant jokes are funnier.
Sexual, no question.
Each their own I guess. When I was in fourth grade oral sex seemed a lot funnier and more taboo so that interpretation seemed funnier. But now, oral sex is only mildly amusing while killing and eating young girls remains both funny and certainly taboo, and so that interpretation seems funnier.
Me, too. I like this version better, because the rite-of-passage thing really works with this joke.
It could just as well be analingus. 
Needs a poll.
(To settle the question in the OP.)
Can I still do that? Even this late in the thread?
ETA: I purposely didn’t put which side of the argument I was so that no one thought to just agree with me to agree with me
Sexual, of course. Otherwise not funny.
Sexual. The humor comes from the double meaning of two words: “eating,” and “brownie.” If you go for the cannibalism interpretation, you’ve only got a double meaning on one of the words. Therefore, that interpretation is exactly half as funny as the sexual interpretation.
Can’t argue with the math, folks.
“Mommy, mommy! I hate my sisters’ guts!”
“Shaddup and eat what’s in front of ya.”
I learned THAT one in the boy scouts!
Definitely. My young boys would find the pun on “Brownie” and the idea of eating someone hilarious, with no idea about the sexual connotation. When I first read the joke in this thread (and I hadn’t heard it before) that’s what I thought: it was a cannabalism joke for very small children.
