Visible crew/equipment: When Michael is street dancing towards the end of the episode, about 5-10 seconds into the routine (as he's shuffling his feet on the floor) look just above the table on the right hand side of the screen. You can easily see a camera crew behind the table. (00:34:10)
Episode #5.5 - S5-E5
Visible crew/equipment: At the end of the episode when everyone has jumped in the pool, look closely in several different shots, you can see a cameraman in the pool filming the "in pool" shots.
