Just don't get stuck standing at the end of the runway with your dyck in your hand when the plane takes off.
I've got a blood test tomorrow for cholesterol levels and I'd much rather have it read off of the palm of my hand in 5 minutes then to have some guy that's filling in for the technician that called in sick poking around in my arm trying to find a vein.
Know what I mean?
Cheers, and good luck.
