Sure, it turns out to be a vacuum joke, but now we know what the writers were really thinking . . .
#2 Smithers Lays His Cards on the Table
You remember this Treehouse of Terror episode, but did you remember how explicitly Smithers opened up about his sexual identity?
#3 Springfield Heights
If you have a keen eye you may get the filthy joke here . . . Hint: schools often use acronyms . . .
#4 Bart Comes out of the Closet
It seems so obvious now . . .
#5 More Wordplay
So it's called 'Sneed's Feed and Seed' because 'Feed' and 'Seed' rhyme with Sneed. It was formerly 'Chuck's' . . . now imagine a couple of S and F words that rhyme with Chuck.
#6 Flanders Pulls A Few Boners
He goes on to talk about going off half-cocked . . .
#7 Homer's Stamina
As a kid we never really got the whole backseat reference . . . or the reference to Homer's 10 minutes. 10 minutes is a good long time, right guys? Right?
#8 Ms. Krabappel's Sex Ed
Can you believe Bart has his eyes covered?
#9 Mr. Plow
Remember when Marge asked Homer to wear the 'Mr. Plow' jacket to bed? Does that make a little more sense now?
#10 Homer and the Apes
This was another head-scratcher when we were kids.
#11 Krusty's Joke
Don't get why Krusty's joke is incredible dirty? Just google the 'Twelve Inch Pianist Joke' if you dare.
