Watch out, there's a magician in the house

Or, to be exact, a magician in the subway and amusement park, in this case. I mostly am posting this video because it had me laughing out loud, and who couldn't use a laugh? But also because I thought this could be an interesting idea to contemplate for a conference: Having someone who looks like everyone else wandering around and surprising people with funny tricks (though the last one in the clip could cause a liability issue if there's anyone with a heart problem in the crowd). Enjoy!
