This Slap Was 100% Improvised! 😂 #MeetDave #shorts

Improv comedy hits entirely different when the actors on screen don't even see it coming. In this hilarious moment from Meet Dave (2008), Gabrielle Union decided to take a celebratory high-five to the absolute extreme. Did you know? The sudden slap was completely unscripted. Union threw the slap so perfectly that it totally stunned Ed Helms, leaving him looking completely lost and bewildered as he tried to process what just happened. Even Eddie Murphy seems to break character for a split second, looking like he forgot they were actively filming. Production loved the raw, genuine authenticity of the mistake so much that they kept the take to make the scene even funnier. What's your all-time favorite unscripted comedy moment in a movie?
