I've thrown on the first disc of the first season of Frasier and the 'I Hate Frasier Crane' with Derek Mann episode came on. I was washing the windows (CAT NOSE PRINTS ARGH IT NEVER ENDS) and not looking at the TV when I heard Mr. Mann say,
"Good, 'cause I was listening, too."
And I actually yelled out,
"OMG! FAT TONY!!"
Of course I checked and it is indeed Joe Mantegna! I can't believe I never noticed that sooner. ^-^
