It reminds me of a newspaper ad I saw 20 years ago which read "Free monkey and 10 pounds of monkey food. call 555-555-5555". Well the gentleman that answered did not have a monkey for sale, and was quite rude about it.

And Wouldn’t monkeys eat regular human food?

Monkey bite your face off.

That number shouldn't work, right?

I am assuming OP is using 555 as a stand-in for whatever number was there at the time, however long ago.
