Fallon's 'Tight Pants' Turns Into Torrid Love Triangle With Will Ferrell, Xtina

One town isn’t big enough for two people with tight pants, let alone three.

Compadres Jimmy Fallon and Will Ferrell were joined by Voice coach Christina Aguilera for another round of their bizarre tight pants battle on Monday’s L.A.-based Tonight Show.

While the mayor might’ve declared Fallon’s trousers the tightest in all the land, Ferrell won’t let his former SNL castmate take credit for the heir to the tight pants throne.

Watch the hilarious segment above to see how long it takes for Fallon and Ferrell to nearly crack, then drop a line in the comments.
