I noticed a blooper on this one: When Potsie looks at the clock it reads 11:30 pm yet if you look closely to the window it's broad daylight. Anyone else notice this too?

Joannie to Potsie: "maybe people wouldn't think you were such a nerd."

I love the scene where Ralph's silhouette appears in Ritchie's bedroom.

I said episode 3, I meant number 4, sorry.
