Jimmy Fallon and Jennifer Lopez fight over who has the tightest pants

You’ve got to wonder what the writing process was like for last night’s dance-off between Jennifer Lopez and Jimmy Fallon. Did it stop at, “Oh, Jennifer Lopez is a guest tonight. Let’s put her in tight pants”?

To be fair, Fallon is also in tight pants as the two battle for the title of tightest pants in this Tonight Show clip, which ends with Lopez taking off one of her hoop earrings and threatening to cut Fallon. Their tight pants fight is actually a continuation of Will Ferrell and Fallon’s 2012 competition.

This struggle will go on for eternity.
