“Have you read Marx?” (author Karl Marx) sounds like “Have you red marks?” A popular joke is:
     
“Two nudists were discussing politics. One asks, ‘Have you read Marx?’ The other replies, ‘Damn it! It’s these darn wicker chairs!’”
 
The joke was told by Australian stand-up comedian and actor Shane Bourne and printed in The Age (Melbourne, Victoria, Australia) on December 26, 1995.

How about the two old men, one a retired professor of psychology and the other a retired professor of history… their wives had talked them into a two week stay at a hotel in the Catskills. They were sitting around on the porch of the hotel watching the sun set. The professor of history said to the professor of psychology, “Have you read Marx?” To which the professor of psychology said, “Yes, I think it’s the wicker chairs!”

A joke my Dad made up (says lots bout Dad): A philosopher and a nudist are at a beach resort…
The philosopher asks the nudist, “have you read marx? And the nudist replies, “why, yes! But I think it’s the wicker chairs.”
Edit: completely possible my Dad heard it somewhere else, or perhaps it came to him originally like the many other examples posted. Gotta trust yo pops tho.
