Entrance, one kudos; exits, free

• kudos: Kudos from the Greek κυδος (kydos, literally "that which is heard of") means fame and renown resulting from an act or achievement; by extension is often used as a praising remark. http://en.wikipedia.org/wiki/Kudos

Madame Tussauds is full of famous people.

This recalls another "Museyroom" scene on page 8:
"Penetrators are permitted into the museomound free. Welsh and the Paddy Patkinses, one shelenk!"
