Boat or no boat?
In a season 5 episode (A Fool and His Money), Malloy wins some money from a contest. Not money from his paycheck, it's extra, sort of like "found money." He wants to buy a boat with it, but practical killjoy Reed spends the whole episode trying to talk his partner into saving or investing the money instead.
Fast-forward to season 7 episode Follow Up, in which Reed is hot to buy--guess what?--a boat. And with his own hard-earned money, I might add. (I'd insert an eye-roll emoticon here, but I hate the new emoticons. Ugh!)
(Btw, there are two things in this ep that remind me of Emergency!... one is Royal Dano, who played one of the disputing horse owners; he was in two eps of E! The other is the fact that Reed floated the idea of he & Malloy co-owning the boat and renting it out on days when they're working. Any fan of Emergency! knows there was an episode in which all the guys at Station 51 were thinking of pitching in to buy a boat and, yes, rending it out on days when they're working.)
