The $9 t-shirt deal of the day over at Teefury today mashes up the Tron franchise with The Big Lebowski in “Bowling” by artist spacemonkeydr.

The sale at Teefury began at midnight EST (Wednesday, December 8, 2010) and will continue for 24 hours from then, and once it’s over, it’s gone forever.

The t-shirt design takes the “The Dude” himself Jeff Lebowski (beer in hand), played by Jeff Bridges in the film, and Walter Sobchak (John Goodman’s character, here with bowling ball in hand) and turns their regular clothes into the Tron video game outfit. Hovering over them are three Tron Recognizer vehicles, each with an X on them, representing a strike in bowling (three consecutive strikes in bowling is known as a “turkey”).

With this year marking the 10-year anniversary of The Big Lebowski, we here at Geeks of Doom in conjunction with the awesome crew behind the annual Lebowski Fest are giving away an amazing prize package to the 7th Annual Lebowski Fest.

The event takes place in Louisville, KY on July 11th & 12th, and the prizes include weekend passes, event tickets, Lebowski shirts & posters, a signed copy of I’m a Lebowski, You’re a Lebowski, as well as a 4 pairs of tickets to the different events during the Lebowski Fest weekend.
