Whistle, yup, can't do it. Tried and tried, I don't know where to put my tongue (no comments here plz)
Spit, not a very good spitter. It goes everywhere, I don't have that one blob in the spitoon sort of ability. I realized this when I run or bike and I have that disgusting build up after a long ride/run. TMI I know.
Drink Tequila. Oh I can drink it, but I can't keep from barfing after
