Well, there are too many to post them all here once, but the first one that stuck out as funny didn't start out that way.
Back in the 'ole ticket-book days, my brother and I conned my Dad into letting us ride with the monorail operator. Of course two minutes after getting off the monorail I realized I had no ticket-book (I was about 8 at the time). My Dad was fuming as it hadn't been a great morning already (he spilled hot coffee all over himself on the way there). The driver was contacted and found my ticket book and brought it all the way around, but we had to wait for him to make the entire trip.
One of my Uncle's took the microphone for my Dad's Super-8 camera (yes, I'm in my 30's now, lol) and tried to act like a reporter to make my Dad laugh. It didn't work until we got to the end of Main Street and my Uncle stood next to something one of the horse's had left behind and told my Dad he would stand there with the mic and when someone stepped off the curb into it, looked down and exclaimed "$h!t!" he would look at them and say, "We have a winner in the name that stuff contest!".
At this point my Dad was laughing so hard he let go of my hand and told me to get away from him before he changed his mind and that I'd better be back at 2 pm in this very spot to meet everyone for lunch. My brother grabbed my shoulder and drug me out of there so fast I think I still have the mark.
