ID this movie

I have been trying to remember the name of this movie for awhile now. Mom divorces dad and is left with the children. The oldest boy plays sports (fooball I think).
Football coach teaches the boys that you should always dry off after a shower from the head, to the testicles, then the feet. Coach says he lost a nut by not following these rules.

Oldest son discovers mom’s lover is a cocaine addict and kick him out of the house and out of their life.

I know it is not much to go on, but please help.

I think that was “Mars Attacks”

I woke up out of bed when I remembered this. I think it was First Born

Yes, it was Firstborn. I remember that scene. For some odd reason I loved that movie and had seen it more times than I care to admit. Must be my fascination with Terri Garr.

The oldest son played Lacrosse, by the way, not football.

No, no, no. Casablanca, obviously.

Thank You, Shagnasty, that was it. Another thing that will allow me to sleep nights. Feel bad that it made you jump out of bed though.
