"Dumb & Dumber" - Roadside Diner

Oh man. "Dumb and Dumber," probably one of the most cherished comedies of all time, has reached such an elusive cult status of screwball genius, that each time I watch it, I find myself picking and choosing different scenes for why I consider it great. Yeah, yeah, I'll get emails spewing me out for saying an ultimately flawed comedy is 'great,' but this mid-90s gem is something of a miracle.
The scene: Harry (Jeff Daniels) and Lloyd (Jim Carrey) are at a roadside diner enjoying some afternoon burgers. Lloyd's "Hey Flo" remark is priceless. Then, after an attempt to reverse a superstitious curse goes haywire (Harry throws the entire saltshaker over his shoulder, rather than just the proposed pinch), Harry is stuck with a snot-filled burger courtesy of an angry truck driver. Lloyd then enthusiastically urges Harry to follow his lead: they're going to get even. Lloyd employs a tactic he saw in a film, where the unsuspecting neighboring table picks up their huge tab.
Why we love it: There's the initial chuckle Harry draws from literally throwing the entire salt shaker. More striking, is the manic, childlike reaction Carrey lends to Lloyd: As the angry truck driver looms toward their table, Lloyd shrouds in the corner of his end of the booth, pointing a trembling arm and hand toward Harry. The double take Harry gives to Lloyd is all the more cherished because it is cut short by the short depiction of the truck driver blowing his snot into Harry's freshly-cooked burger. Then, in a remarkable coup of development, Lloyd's plan to get even actually works. Both the cashier and table of truck drivers fall to Lloyd's scheme. There is justice in the universe of movies!
That is until Lloyd brings up the fact, down the road in the van, that the characters in a film who performed the same trick had their throats slit shortly after. "It's a good one!"
Oh man.
