It's time to d-d-d-d-d-d-d-duel 

popular catch phrase from Yugioh. The phrase comes in the opening theme song where the music stops and he yells that famous phrase.

This phrase has been parodized a lot, especially on ytmnds involving Mario, Spongebob Squarepants, Howard Dean, and a few others.

Me: I had it with you. You're going down!
Punk Kid: All right, you leave me no choice. It's time to d-d-d-d-d-d-d-duel!
