Dexter and Mandark in “Unfinished Business”

You did it all wrong, Mandark. I figured out you were copying "Mister Misery" all along, so I played your own game against you. [Mandark pretends to be yawning] And then you have the nerve [throws the "Mister Misery" comic] not to even follow the dumb story! Oh, and one other thing... WHAT IS WITH ALL THIS STUPID QUACKING?!

Mandark

Well, you see, Dexter. I went to buy "Mister Misery" but the store was all sold out. So I picked up a copy of "Dangerous Duck" instead.

And do you know why "Mister Misery" was all sold out? Because I bought them all.

Mandark

Hmm. Well, then. If you bought them all, how did you expect me to know all "Mister Misery"'s new fight moves then?! [Dexter is upset and a donkey appears] QUACK. [teases Dexter and walks away]
