When I was younger, I went on a trip to my cousins ski home in New York. I am from Florida and didn't know any better and stuck my tongue to a frozen pole when one of my cousins dared me to. I dont recommend it.
Oh no, that classic prank! I bet that was painful, I've only seen it on movies.
Haha well fortunately my cousin was like "Oh [BLEEP] I didnt think you were actually going to do it. [BLEEP]" He was like, dont move not even a millicentimeter, Ill be right back!! And came back with a warm sponge and warm water! 
Haha, wow, that's awesome.  Sort of makes up for him playing that prank on you.
