When people have a small brain, they are not smart. In comparison, their brain is at least 2 times smaller, but in rare cases can be even smaller. Small brains usually: are brown haired, play volleyball, have a twin, named Madison.
Who’s that?
Oh that’s Madison, she’s a small brain.
Aw, poor thing.
