The Season 6 episode “The Love Spell Potential” finds the boys playing “Dungeons & Dragons,” with Howard serving as dungeon master for the first time. He gets into the role by performing impressions in the context of “D&D,” like Nicolas Cage narrating the game and the ghost of Raj serving as a spirit guide after he quits the game to go hang out with his girlfriend. Both impressions are strikingly accurate. Then, the girls come back from an aborted trip to Las Vegas and say they want to play. Because they’re down a player, the guys agree. Howard welcomes them to the game by doing an impression of Al Pacino in his famous “This whole court is out of order!” scene from the movie “…And Justice for All,” yelling, “You’re playing ‘D&D!’ You’re playing ‘D&D!’ This whole apartment is playing ‘D&D!'”
In the blooper version, Simon Helberg goes deep with the Pacino impression, dragging it out for a long time as he moves his hips and works his mouth in a very exaggerated version of the legendary actor’s signature style. He cracks up his co-stars. Jim Parsons is laughing genuinely, not in character, and Mayim Bialik even applauds a bit. It’s a very funny moment where Helberg gets to show off a part of his comedic repertoire that he doesn’t usually get to display on the show, and that’s why it’s the best Howard blooper in “The Big Bang Theory” history.
