In the opening scene there is no pot with pens. Several seconds later, there is.
In this episode, Andy claims to be unable to wash his eyes with water because he has a phobia of putting things in his eyes ("never even used an eye dropper"). However, in Christening (2010), when Andy and Michael are on the bus to go to Mexico, Andy says he'll be needing to borrow some things, one of which is a contact lens case. Clearly, if he has worn contacts before, he cannot claim to have a phobia about things touching his eyes.
