That's an awesome patter idea man, I can actually see myself using this one as
sort of a funny "How easily can you get drunk?" test......
To add equally good ideas to this already existing one,
If you open with this, you can simply ask "How easily do you get drunk?" I think
that's interesting enough to capture attention..... Regardless of what they say
(Even if they say"I don't drink").... say "Well, let's find out.... I can give you an
interesting test that involves absolutely no alcohol and that will tell me exactly
how "sane" you can remain...." and then launch into the effect.
Afterwards, as Jeremy mentioned, poke fun at them a bit that they should
probably stay away from bars and alcohol if they want to maintain dignity.
The only drawback to this sort of presentation is that, while it can VERY
fun, it may not cause the "magic" that you may be aiming for. It depends on
your purpose, theme (if you have one), and what you're planning to do for
the rest of the performance.
If you WANT to create a light, fun atmoshpere, use it. If you want to be
mysterious, etc...... don't
