A Chinese man arranges for a hooker to come to his room for the evening. Once in the room they undress, climb into bed, and go at it. When finished, the Chinese man jumps up, runs over to the window, takes a deep breath, dives under the bed, climbs out the other side, jumps back into the bed with the hooker and commences a repeat performance.

The hooker is impressed with the gusto of the second encounter. When finished, the Chinese man jumps up, runs over to the window, takes a deep breath, dives under the bed, climbs out the other side, jumps back into bed with the hooker and starts again.

The hooker is amazed at this sequence.

During the fifth encounter, she decides to try it herself. So, when they are done, she jumps up, runs to the window, takes a deep breath of fresh air, dives under the bed.....and....finds four other Chinese men!
