Also, on a non-height related note, John Mahoney is actually British. He just lost his accent after serving in the millitary. Sort of coincedental that he played the All-American guy in Frasier yet isn't even American. :]

This guy can look 5'7" with horrible posture but I think when he fully straightens out, he is very close in height with David Hyde Pierce and Jane Leeves. I usually don't upgrade people but I'd say 5'9" for Mahoney. Also, I think Leeves and Pierce need very small downgrades. Leeves to 5'9.5" and Pierce to 5'9.25" but I'm probably being a bit too fussy.

I just watched "Dan In Real Life" and John seems to look a little taller than 5'8,It's just an observation though.
