Once upon a time, I thought it was surreal when I watched a recorded training video of a salesperson explaining the features of a product I had worked on, complete with using silly placeholder feature names I had invented (like "Tunnel Vision" for our VPN) with a straight face.

It's sort of like that watching someone else show me all the results of running that benchmark program I wrote one night when I needed to test something.  The graphs!  They are so much prettier than my graphs.
