It ends up with the poor paralytic insect "running" loose in a cinema. Apparently when it was first shown they doctored some of the seats so as to make electrical impulses tickle random bums. I fantasised about a little old lady who occupied one of those seats and instead of screaming, she wet herself - and was electrocuted.

A skeptical Yank won't hear tell
of curses and demons from hell
till he meets a magician
who (as per tradition)
gets the sticky end of his own spell.

A young man who's done with scholastics
Engages in raunchy gymnastics
With mother's best friend
As folks recommend
He build a career around plastics.

Nah. It doesn't scare me. The only bit of its body that actually moves is the mid-section. The worst it can do is a sort of half-hearted twerk.
