How Could I Have Forgotten?

That, in one single episode of 90210, the following things occurred:

1. Andrea gets hit by a car and the car doesn't stop! She breaks both of her legs! (I do not recall how many episodes she has to wear the casts, but you can bet I will be counting).
2. David and Donna decide to hold of sex until high school graduation, at which time they will revisit the subject.
3. Rick, Brenda's Paris bf, arrives in 90210. She reveals her identity and he loves her anyway.
4. Steve and Herbert hack into the "grade bank" and then run away as soon as it "locks up."
5. Dylan gets accused of cheating on his SATs.
6. Dylan and Brenda break up.
7. Dylan heads on over to Casa de Taylor-Silver and immediately begins making out with Kelly.
