Last night there was a little Late Night Show Swap.... unbeknownst to the hosts! Watch Ryan Reynolds and Will Ferrell fill in for each other on Jimmy Fallon and Jimmy Kimmel!
ABC’s Jimmy Kimmel was supposedly set to welcome Reynolds, while NBC’s Jimmy Fallon was allegedly prepared to interview Will Ferrell, but when Kimmel introduced Reynolds, out came the former SNL star, and over on Jimmy Fallon's show Reynolds entered upon Ferrell’s cue.
