My dad used to drink Mountain Dew like it was going out of style and for some reason, one day he told me it is was panther piss. I looked on the ingredients and when I informed my father of this he told me they couldn't do that or no one would buy it.I believed that it was at least partially true and when I was about 16 and at Taco Bell drive-thru I ordered a 'medium panther piss'. Needless to say I didn't get a mountain dew. When I was about 19 somehow the discussion about it came up and my father almost had a heart attack when he found out that I actually believed him.
