I was driving the kids downstate for a young cousin's birthday. In the back seat my oldest daughter and son were screwing around with the laptop she got for graduation and for high school. They were watching the original batman show on DVD.
We were going through a small town that was having some sort of festival. From the back of the car we heard the theme from the start of the show ("Atomic batteries to speed. Turbines to power. Nanananananananaa...")
My middle daughter who is sitting next to me in the front seat goes "there's the batmobile."
I said "what the heck do you mean batmobile?" and turned to look at what she was pointing at.
We saw this...There was a ton of traffic and by the time I got the car turned around to get back into town to see if we'd had a shared hallucination, the batmobile was gone.
Holy now you see it, now you don't!
