Was thinking just recently about that aspect of Ratchet's original bio and tech specs, the other really main defining characteristic of him besides being the most talented medic on Cybertron and a gruff backtalker was his love of partying and in fact him being such a party animal that it sometimes distracted from his work. Basically the original character sketch was sort of a cross between "Bones" McCoy and Frank the Tank from the movie Old School. Sort of like House M.D. on crack. What's interesting is, from the very get go in the comics and cartoon and on through every other iteration of Ratchet that we've seen, I don't think I've EVER seen that "party animal" aspect of him portrayed or utilized, have we? It is an awesome and hilarious concept to have a party dude surgeon but it seems like every fictional account since has kinda backed away from that...to the point now that most ongoing iterations of him have more as a grumpy, serious, decidedly non-party type dude. But if there have ever been any instances when "party Ratchet" actually surfaced let me know, I'd like to see it.
