Stuttering

[medimus]

"What's your name, son?" the principal asked the elementary student.

"D-D-D-Dav-Dav-David, sir," the boy replied.

"Do you stutter when you're nervous, David?" the principal asked.

"No sir. I don't stutter," the boy answered. "But my dad does, and the guy that fills out the birth certificates was a smartass."
