The Ultimate Comedian's Revenge

Heckling the heckler. The revenge for said comedian is going to the heckler's workplace and bothering THEM while they work.

George: "You should go down to where she works and heckle her."
Jerry: "Isn't that the Ultimate Comedian's Revenge? Heckling the heckler."

Ultimate Eiffel Tower 

Two Eiffel Towers being performed simultaneously. One girl lays across the other girl in an X, while the 4 guys tag team them and high five all at once, creating the 4 columns of the Eiffell tower.

Janet: Dave and Harold lets do an Eiffell tower?

Brenda: Brian and John lets do an Eiffell tower as well.

Brian, John, Harold, and Dave, simultaneously: How about Janet and Brenda lay on top of each other, while they do us, and blow us, and then we high five. Its the Ultimate Eiffel Tower!
