On Futurama last night, Fry was staging a protest outside of a museum to get his fossilized dog back. With a bullhorn he was rallying the protestors with his cry of:

"What do we want?"
"Our dog back!"
"When do want it?"
"Our dog back!"

And before that, Leela was telling Fry that protesting accomplishes nothing. He replied, "Then that is what I'll do."

Bender the bending robot made an appearance on the Simpsons.
