'Cold drink,' eh? That looks like a beer to me. Wait a second... shouldn't recovering alcoholics not drink alcohol?
Oh, wait. The Bush family has never actually admitted that George W. Bush is a recovering alcoholic. They've been delightfully cryptic about his past.
I'm sure this DWI of the President's doesn't come up very often in the White House. Or Dick Cheney's two (count 'em, two) drunk driving arrests.
If you're interested in George W. Bush's past, you should watch these two PBS/Frontline documentaries: The Choice: 2004, and the brilliant and sometimes frightening The Jesus Factor.
