The company that advertises " Hercules Hooks ", those amazing hooks you insert into drywall to hand pictures and other heavy items on are the object of my ridicule. Their add says $14.99 for 10 hooks, and they'll double it to 20 if you order immediately. They go on to say "in fact we'll send you FREE Hercules Hooks for the rest of you life just by asking for them".

Now comes the "Hook" and I don't mean the Hercules Hook. They continue sending you packages of 10 hooks every other month, and billing your bank account $6.34 every time they send them, until you catch on.
