Here's how that scenario really works.
Bonehead hangs a few slices of becan from his clenched teeth and starts jumping rope. Beagle watches for a moment to get the timing down. Beagle takes one leap and lands a strategic bite. Guy falls to the ground and screams. Beagle trots away with the becan.
The only way this ends differently, is if the guy has a taser. Granted, the falling on the ground screaming part stays the same, but the taser gives him a chance to get in a parting shot.
Usually, however, that just makes the Beagle mad...
