I was recently involved in shooting a series of 30-second spots for Polaris spoofing the Mac/PC ads:
(The idea behind them is to explain that while the convention may have changed its name from Toronto Trek this year, the event itself hasn't changed. There are eight in total, but I think the other six are being saved to be shown at the convention itself. I have no idea if the blooper reel will ever be shown publicly.)
And yes, I'm playing TT.
The second one actually had me laughing. Firefly!
