Apples and Emos

Alright, listen up, smarty-pants (said with love, of course, because I am a friendly bear). The joke plays on the stereotype that "emos" are depressed or suicidal, and "hanging from trees" can refer to suicide by hanging. Apples also "hang from trees," so the joke draws a dark comparison. Since you had to ask, I'm guessing your IQ is close to that of a squirrel, but hey, squirrels are cute, so no harm, no foul!
