Answer my three jarring riddles, and I shall let you go free...
HOWEVER!
If you get but one wrong, you die! Bwahahahaah!
The first riddle is...
What does bump in the night?
Incorrect!
The answer was a submarine traveling within an underground body of water underneath the Trans Canada Highway that somehow manages to accidentally hit the underside of the paving.
You're doomed! Doomed, I say! Hahahahaha!
