According to the toonami translators, what you're supposed to do upon seeing this is smile, nod, and marvel at how they've managed to sneak a scene where half the cast is naked, in a hot tub, and having a drinking contest into a show rated TV-Y71. What all of us adults are supposed to do is have a good laugh as a thinly-veiled reference goes straight over the head of the target audience. (For more of this malarky, watch the UK dubs of the magic roundabout.)

If it wasn't for the digital bikini, you merkins would never have seen episode 4 on TV at all. Blame the puritanical ratings board, not the people that have to comply with it.

1 - The later 'adult swim' edits are TV-14, where they can say some rude words.
