10 Genius In-Jokes In The Simpsons
3. Homer's Burnt Tongue
Season 20's "Father Knows Worst" offers up a gut-busting wink-wink gag that's at once extremely naughty but also perfectly designed to sail clean over kids' heads, while also underlining Marge's endearing naivete.
While at the carnival, Homer burns his tongue after accidentally eating a flaming stick and being tricked into drinking lighter fluid by Bart.
His tongue is put in a cast, at which point Dr. Hibbert warns Marge, "I'm afraid his tongue will be in that cast for a few weeks. It may put something of a cramp in your lovemaking."
The obvious implication that Homer won't be giving Marge any oral stimulation for a few weeks is blissfully ignored by her, who replies, "No, it won't. If he wants me to do something, he'll just write it down."
Even with the mention of lovemaking this is a pretty G-rated, kid-friendly joke on the surface, though any adult watching will surely be left cackling at the strange sweetness of Marge's response.
