Haha, last time wasn't all that impressive for me, but there was a lady looking at both ROTF Deluxe Sideswipe and Swerve this past Halloween in the local Newmarket Wal-Mart where I was with my wife, brother and some friends, and she was wondering which one her son would like more. I asked if he'd seen ROTF, she said 'No' as he was too young in her opinion to see it, than I asked what his favorite color was and she said Red, so I told her to go with Swerve.
Than, this past week, I was checking out Zellers at the 404 for new Transformers or Star Wars pieces and an older gentlemen, who looked super confused, asked me if I knew anything about this stuff and I pulled a Sheldon Cooper and said: "I know everything about this stuff."
Long story short, I helped him track down a Clone Wars Turbo Tank and Turbo Tank Support Squad set for his nephew's christmas present...if that doesn't make him the favorite uncle, I don't know what will.
