I can't believe my local supermarket doesn't carry duct tape anymore!
Just use a ball gag. Or shove a sock in their mouth.
They don't seem to have ball gags there either. I'll have to improvise!
Go to Boston's combat zone.
You seem confident in your recommendation. Spent any time there lately?
You do NOT have to go to the combat zone to buy ball gags in the Boston area. Also, I thought it wasn't still active?
Also, come to think of it, that should probably be on my list of places to sightsee at some point, even if (especially since) it is defunct.
