Jimmy Kimmel being pranked with elephant toothpaste in his office is a fun watch

When you combine Jimmy Kimmel being on vacation with a science-themed YouTuber guest-hosting his show, there's only really one viable outcome.

In the clip above, Mark Rober teams up with "Science" Bob Pflugfelder and Guillermo to fill Kimmel's office with elephant toothpaste (basically expanding foam made using hydrogen peroxide), before calling the man on vacation to show him the results.

Kimmel's response? "My attorneys will be in touch."
