"You look happy," said Liz to Jack on 30 Rock recently. "Did you just have a root beer float?"
Thrill your office this end-of-summer. Go get vanilla ice cream and root beer (straws nice but not necessary). Announce a 3:30 pm root beer float party. At 3:25 make the root beer floats. And be happy.
And then join Snoopy for 3 minutes  while he gets drunk on root beer floats to big band music and does his Happy Dance . . .
