63 Bloopers in Friends That Have Somehow Gone Unnoticed By Most People

Viewers never rest assured why the subtle changes of the same scene on set get switched around to be different. Do minor background changes make a big difference, or is it just a change made due to a particular preference?

In season nine of Friends, viewers get introduced to Snufflebumps. During the scene where the nanny is engaging with Snufflebumps and Grumpus, the actor switches the puppets to the opposite hand before he is back in view of the camera. We see no reason for this switch, other than to mess with the viewers.
