Guardians Of The Galaxy Vol. 2: 10 Funniest Moments

Early on in the film, it is revealed that as a result of the fact that he didn't have a father growing up, Peter used to tell the other children that David Hasselhoff was his dad. And that the reason he was never around was because he was busy either filming Knight Rider or touring with his hand.

Later on, after Peter's real father, Ego, makes his villainous role known, he begins to taunt and berate his long-lost son. This taunting reaches its apex when Ego actually transforms into David Hasselhoff as he shouts at Peter. And it is every bit as funny as it sounds.

Though he was only on-screen for a split second, Hasselhoff's cameo appearance manages to be one of the funniest scenes in this already hysterical movie. This bit is so outrageous, so abruptly funny, and so unexpected that it's hard not to put it high on this list.
