-->'''Schroeder''': I heard that!

[[AC:Live Action TV]]
* Barth's catchphrase in the Barth's Burgers segments of ''You Can't Do That On Television'', usually when the kids say "What do you think is in the burger?".
* ''Series/PowerRangersOperationOverdrive'' has this in the episode "At All Cost"; Red Ranger Mack and Yellow Ranger Ronny are playing foosball:
-->'''Ronny''': I've never lost.
-->'''Mack''': Yeah, nor have I. Granted, I've only played Spencer, and that's not much to brag about.
-->'''Spencer''': ''(through the vents)'' I heard that.

[[AC:Radio]]

[[AC:WesternAnimation]]
* In ''WesternAnimation/TeenageMutantNinjaTurtles2003'' episode, "A Better Mousetrap", Splinter left the room. Next thing is that Michelangelo makes a pose and imitate his quote.

* Shendu does this to Valmont in ''WesternAnimation/JackieChanAdventures''
