- Eating whole fruit with the peel nonchalantly (limes usually, but my favorites are bananas)
- Miscellaneous lighter tricks involving filling my hand with butane or putting out jet lighters with my thumb/tongue
- Sticking straws deep into my sinus (Google human blockhead)
- Holding cocktail straws and cards with my tongue
This is just what I can pull out on short notice at a bar. Once people find out what I do, they're usually interested in the details too.
Oh I do that one all the time as well, it's a great way to light oil candles off each other (if you can withstand the heat)
