"The Simpsons" Sideshow Bob's Last Gleaming (TV Episode 1995) - Yeardley Smith as Lisa Simpson

Bart Simpson : [Unbeknownst to Lisa, Bart is not wearing any underwear] Ahhh! Free and easy, Lis'! There's nothing like an unfurnished basement for pure comfort.

Lisa Simpson : Huh? Bart we need to get out of here! Mom and Dad are probably worried sick!

[She hears someone approaching]

Lisa Simpson : Shh! Hide!

[Both her and Bart leap into a nearby bush as the Colonel and his aide walk past]

Col. Leslie "Hap" Hapablap : You know what really frosts my Kelvinator? That coward is still laughing at us from his damn hidey-hole.

Private : I'd rather take an order from Bill Clinton than have to listen to that guy's snooty, high-toned voice again, sir!

Lisa Simpson : [after the Colonel is gone] ... High toned voice... Bart, that's it! I know where Sideshow Bob is hiding!

[Lisa runs to Bob's hideout, with Bart following]

Lisa Simpson : When Bob was on the TV earlier, his voice was higher that normal, and what makes your voice high?

Bart Simpson : Tight, binding underwear?

Lisa Simpson : Helium! Sideshow Bob is in the Duff blimp!
[Bart isn't wearing underwear]

Bart Simpson : Free and easy, Lis. There's nothing like an unfurnished basement for maximum comfort.

Lisa : What are you talking about?
