S1E2 Timmy's Hiccup Cure

Kid is struggling with a bout of hiccups, and he and Timmy become intrigued as they attempt various methods to cure them, but nothing seems to work. Eventually, Timmy, feeling exasperated, kicks a beach ball under the seesaw in frustration. The sudden loud pop of the ball interrupts Kid's bouncing and brings his hiccuping to an abrupt halt.
