The Noches pie scenes have been going on for years. More than a dozen, I'd say, scattered across YouTube... They're all a similar setup with the pie catapult and goggles. Also, the sidekick (not the clown) invariably gets pied by the guests afterwards.
On the plus side, they almost always use females in one or both slots, they do the skit WAY more than Fallon, and the pies are generally better.
There's also messy bits where 3 celebs get slimed with different substances against a backdrop... That one's pretty good. And there's a "model with buckets" one that is usually 2 girls and 2 guys but rarely amounts to much. Still, it's worth going through old episodes of the show to find the messy bits.
I've seen about 4 or 5 of the ones Rich refers to. This is one I hadn't seen. Two beautiful women get plastered with goggles. Still a nice aftermath. Scene begins around 21:30. https://www.youtube.com/watch?v=8O_mOJaBtX0
This one I have seen. Worth showing in case some people haven't seen it. Beautiful Lorena Rojas with no goggles around the 16 minute mark. https://www.youtube.com/watch?v=JHR5lY4EOT4
