I always thought this SNL bit was funny

First Citiwide Change Bank -- WE MAKE CHANGE

(thanks for the link to the snltranscripts)

Bank Representative: We have been in this business a long time. With our experience, we're gonna have ideas for change combinations that probably haven't occurred to you. If you have a fifty-dollar bill, we can give you fifty singles. [ SUPER: "We can give you fifty singles" ] We can give you forty-nine singles and ten dimes. We can give you twenty-five twos. Come talk to us. [ SUPER: "We can give you twenty-five twos" ] We are not going to give you change that you don't want. If you come to us with a hundred-dollar bill, we're not going to give you two-thousand nickels.. [ SUPER: "We're not going to give you two thousand nickels" ] - unless that meets your particular change needs. We will give you.. the change.. equal to.. the amount of money.. that you want change for!

I think this is mentioned in _Demon of Our Own Design_ when he is talking about efficient market theory. Don't have the book in front of me and don't remember any other details...
