this man walked into a diner and he sat down at his favorite table and ordered his usual meal. he is sitting there eating it when he hears some people chanting over in the corner of the diner. he doesnt really think anything of it cuz there are usually wierd people who come to that diner. but it doesnt stop. it is this group of people over in the corner chanting, "72 days! 72 Days!72 days!"

he finally finishes his meal and then he finishes his dessert but the chanting has still not stopped.
he pays his bill and then goes over to the table to find out that all the people chanting are actually blondes. he asks what appears to be the "we figured out a puzzle in 72 days that said 3-5 yrs."
