The Gamer in the Grease - S5-E9
Continuity mistake: Fisher is putting a glove on his right hand when Dr Saroyan walks in. It cuts between them a few times, then we see him turning to the table to explain about the bones and neither of his hands are gloved. A short while later he turns to put on gloves - he regloves his right hand, it goes back to Dr Saroyan for a second, then back to him turning towards the table and both hands are now gloved.
