Dragon Ball Z, Season 3

Frieza:
Well, well. You certainly surprise me with your newfound force.

Vegeta:
And I'm just warming up, you clown. What you just witnessed was only the beginning of my power. If you had one of your stupid scouters here, you'd realize my true potential and you'd run like the coward you really are. No matter. A Saiyan loves a good fight. And you'll discover my powers soon enough. So lets stop talking and cut to the chase. This time, you're going down. What's the matter? Is your brain another one of your weak and underused muscles.

Frieza:
Very well, you've had your fun, but I really do feel sorry for you now, because now you have to back up your delusional, pathetic taunts, Super Saiyan.

Vegeta:
Shut up!
