I routinely use a regular butane lighter as a bottle opener. Doesn't seem very entertaining to me but it seems to generate awe in the masses.
Never have understood why people couldn't figure that one out. Easy to do but you can drop jaws.
I'm only 5' 8" tall but can kick over a 6' 2" persons head. Always seems to surprise someone when they find your foot an inch away from their face.
I'm 6'3" so I will refrain from letting you try that on me.
