@@lalaithan Oh, there are a bunch of them, though the best one is the "I never played with bo..." blooper: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pHXg9oKoWak.html
The ones that play the most serious characters have the best bloopers. Jolene Blalock (the vulcan Science Officer T'Pol) in Enterprise has some really good ones, too, for example.
Watch the episode with Dom DeLuise , Christopher Judge couldn't keep a ' straight face ' so they had very little scenes together . They would ' shoot ' scenes with Christopher Judge and Dom DeLuise separately and then ' splice ' the footage together .
