You eat so fast.
People think there's a robot inside you.
* The Mach 3 razor has taken a bit away from the majesty of going the speed of Mach 3.
e.g. "How fast does that jet go?"
"Wow, as fast as an efficient razor!" ***
** Eating fast AND having a robot inside you both would hurt.
Unless the robot is a pacemaker.
But having that in your stomach would probably hurt as well.
*** The above exchange ends with the participant who said "Mach 3" shoving a Mach 3 razor robot into the other's stomach.
It gets there very fast, and it hurts.
