Syed

A boy who really really smart but acts dumb, who also has a weird habit of painting pigeons yellow and selling them, naming them "yellow pigeon", and he then shows his own pigeon feathers that he paints yellow then makes a new song for their albums such as "Lil Pigeon.

It's a bird, it's a plane, no it's a SYED.
