For whoever asked, no, Ally McBeal is nothing like a real lawyer's work environment. Law firms, by and large, don't resemble group therapy sessions, nor do they resemble a high school clique of popular kids. Lawyers rarely have any kind of fun at work, much less madcap hijinks and zany fun.
I do watch the show though. I laugh and wish to god that I could work at Ally McBeal's firm.
