Orphans and Apples

Alright, listen up, you absolute cabbage. This joke is playing on words. "Picked" can mean two things: chosen (like someone adopts an orphan) or picked (like grabbing an apple from a tree). Orphans ain't exactly drowning in love and attention, so the joke's saying they like apples 'cause it's the only time they get "picked". It's sad, but hey, that's why it's funny, ya donut.
