For those referencing the SNL skits, they actually don't bring that up. All the ones I've been in had the 50s drive-in thing going.
The one near me had a 1 pound burger challenge. Actually started with 20oz of ground beef so you got a true 1 pound burger, loaf of bread or so bun, lots of stuff on it. Think I was undefeated in 3 attempts at it and one friend finished off 1/2 a milkshake, 1/2 order of fries and his burger, then ordered the 1/4 pound burger too.
