I dunno if this counts but I saw a guy accidentally own his kids. He had one of those double strollers and was walking down the little incline next to California Screamin'. He dropped his sun glasses and bent over to pick them up. All of a sudden his stroller starts rolling away from him at a very fast pace. He yells out "No! Aw no!" and the stroller randomly flips and lands on it side. Once I knew the kids inside were ok...my friend and I couldn't stop laughing...and then we saw Bob Sagget! He just standing around looking for fans I think. No such luck for Bob tho.
And...I sorta owned my girlfriend and her brother. We were in the spike room in the Indy line and she we were having an argument so I casually lean against the pole and suddenly "BOOM!" the spikes come down. As soon as she heard this she ran out of the spike room and dug her nails into her brother's back. 'Twas funny.
