Two questions arise from this. A: How do they come up with this sh*t? B: How do they manage to convince bona fide celebs like Jennifer Lopez to take part in the batsh*ttery?

Lopez, recently single once more following all the cheating that her ex-Casper Smart was allegedly getting up to, put her best foot, pair of skin tight pants and '60s Beatles era wig forward in this bizarre sketch with Fallon where they battle over having the tightest pants through song and dance. It's a great move for JLo seeing as she not only looks whopper but also can't look, sing or dance worse than Fallon so she's going to come out on top regardless. It's also a nice middle finger to Smart to show that she's actually A-ok post-breakup, which we always commend.

And anytime JLo goes back to her Jenny from the block roots, we also approve.
