Rachel met Chandler 3 times, and each time she met him it was like they never met.

1) First it wasin the very first episode of friends..when she ran away from her wedding,where Monica introduced Rachel to everyone and also to Chandler.

2)The second time was in the flashback, when Chandler was trying to hit on Rachel..that is when she was engaged to barry..and wanted to have meaningless s*x with some one..and chandler comes in

3)The third time was during the Thanksgivings, when Ross brought Chandler home and introduced him to his family and Rachel

and then again..

she once made out with chandler during highschool dance?

correct me if i am wrong..
