Welcome
Enter Notorious Villain
No weakness to my rhythm
Don't need a shot of penicillin
I cause a pause,
when your rhyme falls
like when you read the fine print
of a newly signed clause.
Your stuttering
Butterfinger BBs have you stumbling
A numbing sensation is now
crawling in your stomach.
Did you hear something?
(Growl)
Are you hungry?
Or are you anxious
probably nervous
That your stomachs
fumbling.
Does this
sound of mine truly
and dearly beloved doily
we are gathered here today
to witness this man drooling
Call an ambulance
He just lost his stance
A minute ago he was standing
Now hes convulsing in my trance.

Hmmm. I liked this a lot. I like the butterfinger part the most.

I like this better than the other of the ones you posted. Smoooth.
