Well, at least the dare isn't something super difficult. Tamaki easily flips over into a handstand.

As for the "I'm a Little Teapot" part... it's an English nursery rhyme, but he kind of knows it.

"I'm a little teapot, um... short and... round." Maybe. "Here is my handle, here is my spout. When I get..." When the teapot gets what? Full? Hot? It shouts something, right? "When I get angry, hear me shout. Tip me, uh, over? And pour me out."

Then he flips back over. Nailed it.
