Was that guard with his recites named "Sean" ?
Correct!

So here’s the original:
There once was a girl named Sally, who ran business from an alley ...
Always snappy, her clients were happy, until she presented the tally.
And here’s the translation:
Einst lebte 'ne Dirne namens Michelle, verdiente ihr Geld in einem Bordell ...
Im Dunklen sie stets das Vorspiel begann, doch dann - oh Schreck - Michelle war ein Mann!
That cracked me up!
