I saw a Brady Bunch like that one time. Greg really was smoking, but he promised he'd stop and then a pack of cigarettes fall out of his coat, RIGHT IN FRONT OF MRS. JOHNSON who's the head of the school's anti smoking committee! And Carol was on that committee!!! Was, as in, she was removed after that embarrassing incident. And then, Alice realizes that Greg mistakenly took home someone else’s coat, and you know who it belonged to? Tommy Johnson, Mrs. Johnson's son (he and Greg are in a band called The Banana Convention and sing “Til I Met You” which was totally groovy.) And then, at the end, Tommy admits the smokes were his, and he tells his mom, and she apologizes to Carol and offers to let her back on the committee, but Carol says “You can take your committee and ram it up your...” and then the credits come up.
So, long story short, it could happen.
