The bunny ears thing is a good idea (quite funny!)
I went to Alton Towers (a theme park in England) a few years ago with many friends. I go each year and know where the cameras are so we decided to do a different pose on each ride!! We all started quite well as we started on the tamer rides, but then we got to Oblivion which in a 120ft(I think!) vertical drop into a hole in the ground!! We agreed we would all do a simple hands in the air, and whio was the only idiot with their hands in the air on the picture.... you guessed it .... ME!!!!
I love white knuckle rides!!
