WTF moment

Today I didn’t go to the gym at lunch (going after work) and instead went out to get dog food for Nicki. On my way back as I am almost back to the office when an older guy, mid 50’s maybe goes driving by me in a convertible Lotus ($$$)with the top down. I see his arm out the drivers side and his hand moving all around, at first I assumed he was gesturing, being an ass, who knows. As he goes past I notice not only is his hand moving but his entire arm and body as well in a Dr Roboto/Hand Jive/Snake Charmer/I just hit the lottery, kind of way. He has his arm fully extended out the side, wiggling it all around. He obviously was quite content about something. I can only imagine what that might be.
