We’ve picked our random twitter tweeter and that lucky user is @paschott. He wins a $50 gift certificate to ThinkGeek. Don’t forget – you can still get a great holiday deal by saving $10 on any order of $40 or more at ThinkGeek by entering the code GEEKDAD55PD during checkout. Check back tomorrow when Dave G. will have another fun giveaway. And don’t forget – the puzzle will be an all new contest in 2011!
