Spongebob Squarepants - Magic Tattoo
In the episode where Spongebob is trying to get into the Salty Spitoon bar, he has to prove his toughness. Sandy proves hers by ripping off the bouncers tattoo and flipping it upside down. It said mom, but now it says wow. Later the camera is back in the bouncer, and the tattoo is right side up, however, the word still says wow as if it were still upside down. Later it is fixed and all is right side up! On the other hand Spongebob gets in to the bar and slips on an ice cube.
