Look at one of the monitors on a desk upstairs at the Ghostbusters headquarters. You can see the ending screen from Ghostbusters on the NES.

One of the messages from the Vigo painting is a reference to the O.J. Simpson trial. It reads, "I see the evil in the times to come. The glove won't fit."

Look at the wall behind Peter's desk. Some of things found there are funny.

Newspaper clippings: "Teacher's Death was Natural", "OMG Ten Ghostbusters They are Gonna Blow Your Mind" , "Beware Central Park at Midnight" (good advice), "Vigo Painting Melted: It was awesome when it exploded"
Degrees: "Your Name Here", "Hey", "The Big Apple: To the Cause"

Check your messages when you get back from the Stay Puft Marshmallow level. The new person's father or friend says "You're doing adequate work out there Luke, keep it up!". This reveals that his name is Luke Hoss.

When using your PKE Meter to track Slimer, go up to Room 1206, to the right of the vase he is hiding in. The sounds coming from the door are of a man and a woman arguing (or doing something else).

Slimer disappears from his small cell, with no damage to it, before Shandor releases all the ghosts from the containment unit. However, after the Ghostbusters return from Shandor Island, Slimer's cell is all torn up.
