hmm.....I guess my sense of humor doesn't cover that front, I don't see the humor. Its too sadistic (probably wrong word, but I don't care). Its not a trick or anything, the tree is not a thinking entity..if it was maybe it would be more funny. I dunno....its probably just me.
I see the humor and I like those comics. Some of 'em are pretty funny.
BTW:
Q: What do you call a gay ape?
A: Homo-simian! :lol:
Thatt's funny to me because a friend of mine at work and I were discussing the new laws that have been passed which give the great apes basic human rights. He kinda made a joke wondering if they would be allowed gay marriage... and I thought of that joke.
