“Please do not attempt sex. As years of exposure to TV radiation have left your genitals shrivelled and useless.”

I don’t know the episode, but the joke is about the TV broadcast experiencing difficulties. The broadcast warns against any sexual interactions to pass time because years of TV radiation shriveled up their genitals.

“Two Dozen and One Greyhounds”

S06E20

“He’s got the precious cable TV cable!”

I’m taking a swing here but I’m gonna say it’s the episode Homer’s Barbershop Quartet. I think this is when Chief Wiggum is watching all the talk show hosts make fun of his attempt at a solo career after getting kicked out of The Be Sharps.
