My oldest known joke

[Borg warner]

I heard this one in 1959 when I was in the sixth grade:

An Englishman, a Frenchman, and a Mexican go to a hotel to get rooms and the hotel maid goes to them and says, "I apologize for the inconvenience, but your rooms are not ready yet. I need to know how many sheets you would like on your beds." And the Englishman says, "I would like two sheets, please." and the Frenchman says, "I would like only one sheet". And the Mexican says, "You sheet on my bed and I keel you."
