Season 8, Episode 11, 'My Soul on Fire, Part 1'. In the Bahamas, after Elliot walks away, an old guy with a drink walks sa pamamagitan ng and says "She's all mad." I'm sure it is a cameo, but who is the guy?

No. Much older. Definately not an actor. Voice sounded familiar. Cameo didn't last madami than two seconds. Dick Dale, perhaps? One of the tabing-dagat Boys?

Maybe it was a scene similar to one that happened in the hospital in a nakaraan episode - and this was a recreation of the same scene in the Bahamas, with the guy in place of Laverne???

It's quite similar. Laverne says it in My New Old Friend when JD and Elliot have just stopped being sex buddies but JD is still in pag-ibig with her. Elliot has all her stuff stolen and really needs a friend, but JD isn't there for her because he's confused sa pamamagitan ng his relationship with Elliot and in stead of helping her goes on a petsa to make her jealous. Laverne witnessed their argument about it and described the events to her husband over the phone, saying 'Now she all mad.'

According to Scrubs HQ, they couldn't afford to take any madami guest stars to the Bahamas, so Bill Lawrence cast himself, and the other parts were filled sa pamamagitan ng locals. So it's just some guy.
