WAIT! I have it. Back in late 2013, I made a 6 second Vine where
   I did the "disappearing shirt" magic trick. You tug on your
   shirt a few times, and it magically comes off. Then you throw
   your shirt back on, and it magically comes back on.

   I exposed thousands to my bare chest for a period of two
   seconds. That MUST be illegal somewhere... or at least highly
   immoral.
