Our tipster says that these photos [click to expand] were snapped at Avenue Nightclub in Houston, also known as 4500 Washington Avenue, on the night of Texas A&M's resounding Cotton Bowl victory over Oklahoma. Manziel was in apparent violation of the Avenue dress code, but our tipster notes that he was there with his father, so it's probably OK.
Now we know what Manziel was up to the night before he was doing this. Looks fun!
Update: TMZ got some pictures too. He has a sparkler in his mouth in theirs.
Update 2: More pictures (there are always more Johnny Manziel pictures) here.
