There was a Duck, a Frog, and a Skunk, and all of them were in line at the dollar theater when the lady said that will be 3 dollars. 2 of them could pay but one could not; who could not pay and why?
The Duck went in ’cause he paid a Bill; the Frog went in ’cause he paid a Greenback, but the skunk could not ’cause he only had a scent!
