Two blondes were sitting in a restaurant. A few minutes later, they stood up, gave cheers, and shout,

“30 days”.

A man approached them who was sitting next to them. He came to the table and asked,

“What are you celebrating?”

One of the blonds replied,

“We bought a puzzle and on the box was written from 3 to 6 years and we made it in 30 days.”
