TV Tropes has a thing for that.
Getting Crap Past the Radar.
From the Spongebob page:
"At the beginning of the episode Your Shoe's Untied, SpongeBob is channel surfing. He comes across a channel with a real orange sea anemone gyrating to energetic go-go dancer-style music which SB finds "entertaining" (leaning forward eagerly in his seat at one point). Suddenly, Gary walks in on SB,who panics and changes the channel to a football game, claiming unconvincingly, "I-I-I-I was just looking for the sports channel, Gary...""
BTW, do you rememberCow and Chicken? When Boneless Chicken was a kite?
On the other side of the lava river was the AHZ-WEE-PAY tribe...or should I say, ASSWIPE...!
