Here's one of my favorites:

Q: Why are there no white M&M's?

A:Because they would enslave the black M&Ms, steal all the red M&Ms' land, hunt the blue M&Ms to extinction, accuse the yellow M&Ms of obstructing trade, start a panic that the little green M&Ms were invading Earth, and complain that the brown M&Ms were taking all their jobs.

I figured maybe the white ones had just stopped breeding after about 1980 or so lol.
