SHELDON (cannonball): Getting INTO the pond is easy. You just cannon ball in. ARTHUR
SHELDON: And the swimming isn't the problem, either. The swimming's great. ARTHUR (Listening)
SHELDON: It's the GETTING OUT that's a problem. You gotta walk through the super gross pond mud. And it's all slimy and nasty and has old leaves and algae and squishes up through your toes. ARTHUR (Looking at Sheldon)
SHELDON (grossed out): Maaaaaaah
GROSS...GROSS...GROSS. ARTHUR: Quick! Don't imagine how much of that consists of fish poop!
