Harry felt the potion go down his throat, trickling down.

"Now," Snape said, holding up a tiny vial. "This is Veritaserum, the one and only, extremely strong truth potion.  What you just drank is is a different sort of truth potion, not as strong."

"Your nose is hooked," Harry blurted out, unable to help it.

"You insolent little-"

"I took a potion, so I'm randomly blurting out the truth."

"Fantastic," Snape grumbled.

"Your hair is as greasy as the chicken served in the Great Hall."

"YOU LITTLE..." Snape was about to burst with anger.

"I can't help it.  I took the potion.  It works really well and you shouldn't be so hard on Hermione."

"Insulting me like that..." Snape clenched his fists. "OKAY, I KNOW YOU CAN'T HELP IT!" he cried. "But go insult someone else!"

"Draco Malfoy is stupid and mean," Harry couldn't help but say.
