[Po slurps up noodles, one ends up draped on his nose like Shifu's mustaches. Everyone starts chuckling]
Po: What?
Mantis: Oh, nothing... Master Shifu.
Po: Oh, yeah, yeah.
[imitating Shifu]
Po: You will never be the Dragon Warrior, unless you lose 500 pounds, and brush your teeth!
[everyone except Tigress laughs]
Po: What is that noise you're making? Laughter? I never heard of it! Work hard, panda, and maybe someday, you will have ears like mine.
[he holds two bowls over his head to look like Shifu's ears]
