One my favorite episodes, Richie shows his how confusing teenage years can be. He starts out trying to get attention of a girl and later finds out he has deep issues with growing up.
The two stand-out scenes are:
1) Richie and Ralph exchanges. Especially, when Ralph reveals his real thoughts of The Fonz. (Ralph: "Take Fonzie... super cool Fonzie... Him with his 'AAAAAY!' ...That's a little sicko when you get down to it!")
2) Richie talking to himself.
In this episode also the first time we get the ideal Ralph is a little cowdardly... he reveals he sleep with the lights on.
