"Teenage Lust" script, Scene H

The tag has the same setting, but the next morning.  In the script, the box of their childhood items was going to the garbage rather than Goodwill.  And Laverne wanted to save her catcher's mitt, which is not as funny as the football helmet in the aired version.  Laverne's closing remark that Shirley is so strange for talking to Boo Boo Kitty was added.

I would say the most significant change from the entire script to filming is that Laverne bonds more with Lyle in the former, which is odd considering they liked the character enough to have him back later.
