10 bridesmaids are getting ready for a wedding. 5 were intelligent and 5 were unintelligent.
They waited at the bus stop to catch a bus to the brides house so they could travel to the wedding with her. the 5 intelligent brought extra money for the bus incase, and the 5 unintelligent did not.
The bus broke down and the bridesmaids had to get off and wait for another bus.
Because the unintelligent bridesmaids did not have any money to catch another bus, they asked the intelligent bridesmaids for theirs. The intelligent said they only had enough for themselves and that the unintelligent can go to the ATM before the next bus comes.
So, the 5 unintelligent bridesmaids headed for the ATM while the 5 intelligent continued to wait at the bus stop.
While the 5 unintelligent bridesmaids were at the ATM, the bus came and the intelligent bridesmaids got on.
