19 Awesome Movie Cameos Nobody Saw Coming

13. John Cena - Daddy's Home

Daddy's Home may have been a thoroughly mediocre studio comedy, but it did at least end with an hysterical punchline, as Mark Wahlberg's Dusty meets his stepdaughter's biological father, Roger, for the first time.

Roger pulls up in a motorcycle as Metallica's "For Whom the Bell Tolls" blares out, before removing his helmet to reveal that he's played by none other than John Cena.

Dusty is, naturally, scared out of his wits in much the same way that Brad (Will Ferrell) was by Dusty earlier in the movie. Dusty tries to introduce himself to Roger, who gives him a curt, "Nope" and bounds past him as the end credits roll.

This was a great surprise that made perfect use of Cena's imposing stature for a killer final zinger. The upcoming sequel will probably stretch that joke out until it's no longer funny, though.
