[Last to board the train, Jerry and Joe meet the girls for the first time.]
A:       Say, kids, have you heard the one about the girl tuba player who was stranded on a desert island with a one-legged jockey?
B:       No.  How's it go?  
C:       Now, cut it out, girls.  None of that rough talk.  They went to a conservatory. 
A:       [mocking] They went to a conservatory.  [blows her trombone] Brrrrttt!

[At Jerry's upper berth during the impromptu party]   
A:       So the one-legged jockey said...
B:       What did he say? 
A:       So the one-legged jockey said, "Don't worry about me, baby.  I ride sidesaddle!"

[At the Seminole-Ritz Hotel, Sweet Sue is giving the girls their room numbers.]

D:       Oh, what did you expect?  The one-legged jockey?
