He crawled from the deep to wreck havoc!... And hang out with his bro

Prefacing this, I may be looking too closely at this, but it entirely seems possible with the numerous references per an episode.

With the way Penny's voice echos and how she falls to her knees seems very similar to me.

It's kind of like a hat on a hat on a hat, (waynes world -> Scott pilgrim -> gumball)

Wondering what's the official way to do it. I've looked it up and people have different ways of doing it. Some people put there middle finger and index up, and some peope include there thumb. Its pritty hard to distinguish what tobias is doing with his fingers.

This has been bothering me for a bunch of months now. I am looking for an episode of I think between Season 2 and 6 where Gumball and Darwin cringed so hard that their faces folded in on themselves and Gumball said "I cringed so hard, I..." something on the lines of that. Can someone PLEASE help me find this ep?
