I have come close to accidentally juggling them. I have a couple that will, without fail, strike and wrap while hanging half-way out of the tub. The juggling happens when trying to catch said snake with rat attached when the strike was a little too enthusiastic. Then I have others... must be a full moon, raining, with the wind out out of the east before they will eat anything. I am exaggerating a little of course, but such extreme behavioral differences in a single species always amazes me.
