A pianist was hired to play background music for a movie. When it was
completed he asked when and where he could see the picture. The
producer sheepishly confessed that it was actually a porno film and it
was due out in a month.
A month later, the musician went to a porno theatre to see it. With
his collar up and dark glasses on, he took a seat in the back row,
next to a couple who also seemed to be in disguise.
The movie was even raunchier than he had feared, featuring group sex,
S/M and even a dog.
After a while, the embarrassed pianist turned to the couple and said,
‘I'm only here to listen to the music.’
‘Yeah?’ replied the man. ‘We're only here to see our dog.’
