Magnum P.I. himself,

Tom Selleck, will guest-star on the Feb. 21 episode of ABC's Boston Legal. In a role written for him by series creator David E. Kelley, Selleck will play Ivan Tiggs, the eccentric and cocky ex-husband of Candice Bergen's Shirley Schmidt, whom he asks to be the best man at his wedding to Monica Geller. Oops, sorry. [Sigh] I miss Friends.
