You there, having the yard sale. Up against the wall, and put your hands over your head.
From the Consumer Product Safety Commission's handbook:
This handbook will help sellers of used products identify types of potentially hazardous products that could harm children or others. CPSC's laws and regulations apply to anyone who sells or distributes consumer products. This includes thrift stores, consignment stores, charities, and individuals holding yard sales and flea markets.
Oh, no, we don't have too much government, no siree.
