Time for something stupid.
Take any soundbit from your favorite champ and add "in the shower" or "in bed" to them.
I'll do a couple examples.

"Stay positive in the shower!"

"Imagine if I had a real weapon in bed."

"I'll scout ahead in bed!"

"I love it when a plan comes together in bed!"

"Who needs a map in bed?"

Err are you sure not in the wrong bed?

The Yeti knows the way in bed

draven does it all with style in bed

* Guitar solo, in the shower*

"If you'd like to play with me you better be sure you know the game, in bed"

"Size doesn't matter, in bed"

"Hahaha* (in bed)

"Shall we resolve this dissonance?" (in bed)

Enforced equilibrium-in bed.
