Here are the fun show loopholes:
1) Beanie Baby loophole: Although not considered to be firearms by the BATF, these items are being sold by unregulated dealers and to people over the age of 10.
2) Beef Jerky loophole: Also escaping federal regulations, beef, buffalo, elk, etc. jerky is freely being distributed by way of "free samples", much like crack dealers do when they want to hook in new customers.
3) Personal Hygiene loopohole: This is the most insidious of all fun show loopholes. Many of the attendees are following the medieval tradition of only taking 3 baths during their lifetimes: once when born, once when married, and once before being buried. Needless to say the stench eminating from such individuals is overpowering to the point of nausea. This loophole requires serious attention and should either fall under the jurisdiction of the local HAZMAT or the CDC.
