Hulk of a Different Color - S2-E1
Continuity mistake: When the gray Hulk picks Gargoyle up from out of his cockpit seat, he picks him up with his left hand, with his upper knuckles towards Gargoyle's body. When the shot changes to Gargoyle saying "Release me," Hulk is holding him with his right hand, and his thumb and fingers are pressed against Gargoyle's body. (00:12:28)
