Frankie becomes sad when her doctor informs her that her ovaries are shriveled up, which means her days of having kids are over. In an attempt to cheer her up, Mike offers to have him and Frankie babysit the neighbor's baby overnight, which puts some perspective on being an older parent. Meanwhile, Sue and Axl are a bit shocked when romantic sparks fly between Sean Donahue and Sue's roommate Lexie; and Brick tries his best to hone up on his font knowledge when he meets Gibson, a worthy font opponent.

After Frankie tries to get a stubborn Mike to go see Dr. Goodwin to take care of his toothache, Mike convinces the good doctor to leave his tooth alone and tell Frankie that everything was ok. But the two find themselves fabricating a story that's so ludicrous that they fear Frankie will figure out the truth. Meanwhile, since they are nearing the end of their senior year at college, Axl, Hutch and Kenny decide it's time to sell the fabled Winnebago; Sue tries her best to let college golf cart driver Tyler know that she likes him; and Brick attempts to write a historic Scottish rap musical - a la "Hamilton" - focusing on the life of Sergeant Charles Stuart MacKenzie.
