I'm the grumpy old troll who lives under the bridge. If you wanna come over, all you have to do is this. All you have to do is this:
Solve my riddle -
They call my Mr. 325,
Don't leave your shoes untied.
You might want an anti-emetic,
You also might want to have an EpiPen handy.
I am not something you put your cup down on,
I wood get to the point, but I don't want you to shriek.
The grumpy old troll intro does have something to do with this riddle!
