From the many hilarious moments from Rat Race , the Disaster Dominoes scene which lead to a Nazi car crashing into a WWII veteran convention, complete with a "Hitler".
A brief summary: Jon Lovitz's character has stolen Hitler's car, burned his middle finger and his tongue on the cigarette lighter, and hit his upper lip on a lipstick smear on the steering wheel, resulting in him appearing to have a Hitler moustache, speaking in German-sounding gibberish, and flipping off the crowd of World War II Veterans. The best part of all this? The character (pretty sure the actor too) is Jewish.
Randy: ARE YOU INSANE?! THIS IS HITLER'S CAR!!
Never forget the Squirrel Lady.
Cue skeleton with bag of nuts.
"And your hat!" "Why my hat?" "For her... her... VAGINA!" (it's hard to choose the funnier face, Cuba saying that last word or the bus' driver reaction)
Duane and Blaine sabotaging an entire airport to the tune of 'In The Hall Of The Mountain King'. When Duane ends up driving up the tower with Blaine screaming as he climbs up, it's just hilarious. The musical timing is great too.
The Cody brothers decide to double their chances of winning and Duane ends up clutching onto a hot air balloon. He is shown colliding with cows and fighting with the hardware store guy, while Blaine ends up crashing a rental car into a lake. The classical music just clinches it.
(while clutching the rope of a hot air balloon entangled with a cow)
Duane: Give me my key!
Hardware Store Guy: What're you talking about?!
Duane: Give me back my key!
(they start fighting)
Nick Schaeffer tricking the organizer of the race into donating a good chunk of money to charity at the end of the film.
One of the best brick jokes ever. Enrico is a narcoleptic and, once the race starts, falls asleep before he even gets out of the casino. The movie then ambles along long enough to almost forget about the character completely. After about 45 minutes of hijinks, the film finally cuts back to Enrico still asleep in the hotel lobby. And he's STILL the first to arrive to the money...and falls asleep AGAIN!
"I make a joke, to help you forget how screwed you are." Atkinson's Italian accent putting such emphasis on the word "screwed" makes it much funnier than it would otherwise be.
Sinclair's efforts to get the race started.
Merrill: So, when you say "go", you mean, just go?
Donald Sinclair: Uh, begin, commence, start moving... theoretically you have been racing for about forty seconds now, and so far Mr. Schaffer is winning because he's nearest to the door.
And then Enrico leans forward to look.
No one moves after this, so Sinclair rolls his eyes, pulls a gun, and starts firing at the ceiling.
The scene on the I Love Lucy convention-going bus. The bus veers off course, the soap in the bathroom starts filling up the bus, but Owen refuses to stop, and it plays out like an episode of I Love Lucy. Minus the tons of other Lucys, of course.
Lucy: How about a pit-stop? Owen: Sorry, this is a one way flight. There's a bathroom in the back. Lucy: The latch is broken. Anyone could just walk right in. Owen: So? You ain't got nothin' these other Lucys haven't seen before! Lucy: ...Not necessarily. Owen: (disgusted) GAH! Lucy: (annoyed) Please, would you stop screaming? Owen: Damn!
Said Lucy has a hilarious "Ooh, I'm enjoying this" face when Owen starts taking off the bus driver clothes.
