Dr. Townshend: What the hell's this all about? Dr. Kelso: Nothing! I was, uh, just looking over your files and, um...well...your osteoporotic patients aren't on Bisphosphonate; your diabetics aren't on ACE inhibitors. Doug, a lot of your treatments are pretty out of date. Dr. Townshend: Come on, Bob, I'm--guys like us, we're set in our ways. Dr. Kelso: Well, this is not an age thing, Doug. Hell, these days if you've been out of med school five years, half of what you learned is obsolete. Why do you think I spend every other weekend at a seminar in some two-star hotel ballroom that still stinks of last night's prom vomit? I do it because I have to keep up. Dr. Townshend: Also, it gives you two days away from the missus, right? [laughs] Once again, I am sorry I was the one who introduced you in the first place! Dr. Kelso's expressions remains serious. Dr. Townshend: Look, Bob, I just...I don't have the energy for all that stuff. Dr. Kelso: Well...then we got a problem.
