The Amazing World of Gumball, Season 2

[The episode opens at the video store, where Gumball is trying to rent a movie, but, inexplicably, an invisible barrier is standing in his way as he struggles to put the film on the counter.]

Larry:
What's wrong with you this time?

Gumball:
(straining) This movie is so sucky, my body refuses to rent it.

Larry:
Then don't rent it and get out of here.

Gumball:
NO! I promised my sister!

Darwin:
(takes the movie from Gumball) Here, let me try.

[Darwin runs to the counter, but the barrier emits a powerful force that knocks him back, causing him to fall backfirst.]

Darwin:
You're right. This movie's so bad that every atom in my body refuses to pay to see it.

Carrie:
(views the film's cover) Oh, come on. It can't be that bad. (gasps) A Pony's Tail?
