There was a period back in the 80's where I decided I wanted to dabble with magic. So, I spent some time at a couple of different magic shops and read a few books and began doing a few tricks here and there at parties. It was super fun.
There was a brief period of time that I started working kids parties (I did about half-dozen paid gigs) and the last time I ever did a "show" for kids was at my friend Duane's house for his daughter's birthday party.
I did this classic trick where I made a cone out newspaper then I took a pitcher of milk and poured the milk into the newspaper cone and then opened up the newspaper to reveal that the milk had disappeared. The kids were totally amazed (as were the adults) but since that was my last trick, I packed everything away, brought my bag upstairs and went to hang with the adults.
About five or ten minutes pass when I hear Duane's wife scream "Chris! I am gonna kill you!" Evidently the kids liked the milk trick so much that they had decided to try it out for themselves and ended up pouring the better part of a gallon of milk all over the basement floor. Good times!
