Home Improvement/Heartwarming


 * When Mark comes down with chickenpox, Tim (who's never had it) has to move in with Al temporarily. Hilarity Ensues, natch, but then Tim explains why he always makes fun of Al - he considers him to be like one of his brothers.
 * Also featured is a neighbor that Al has a crush on, who he tries to impress by saying he hosts Tool Time and Tim is his assistant. Though annoyed, Tim begrudgingly goes along with it - only to later let it slip by accident that he's the host. When Al's about to come clean over lying, Tim intervenes by calling Tool Time "our show."
