Sinise is one of only a few real class acts to be found among that whole community of jackasses. The only other top-notch personalities I can think of there are Bruce Willis and Tom Selleck. The rest are pretty much worthless...
Don't forget one of the best ever -- Charleton Heston.
Sinise also appears sometimes on KABC radio in Los Angeles on
The Al Rantel Show.
He sure does act like a stand-up guy, that's for sure.
