I had one!
I got it from this kid in my school who was like, on his third year of being a senior. And I was like, "No worries, you'll get out of here before your son graduates."
Then I was like, "Woah! That should be a sitcom!"
It could be called, "Locker Buds" or "Dad and Josh" or something. Anyway, I already have the basics of 2 episodes:
The first ep would be his dad trying to get his son to let him cheat. But his son tried to teach him that's wrong. It didn't work out and lead to that oh so original Hollywood comedic twist and moral?
The next ep would be his dad accidentally stealing his girlfriend's heart. And how much that would suck for him.
Great, no? Oscar award winning, too kind.
Now, post your sitcom ideas! Go go!
