How he looks
There's a Jan. 18th comment in the Grandpa Muster thread about Sean's complexion, but I'd like to just focus on that.
He's a drunk, right?
Watching him on Bill Maher this week, he's got that deep red color that seems to be a big identifier with drinking lots of alcohol.
Apparently he's still highly functioning, but this has to be detrimental to one's health.
And from the history he doesn't seem to be a happy drunk.
