I usually don't watch this show, but I caught one eppy when Marge was mad and Homer because it was her birthday and he bought her a bowling ball, which was really for him. Marge started to learn how to bowl, and got involved with another man, who kept coming on to her.
Lisa and Bart noticed that thier parents marriage was "falling apart" and Lisa was in Stage 5: Self Pity while Bart was in Stage 3: Fear.
Needless to say, it was hillarious! And I so enjoyed it
