Sour Grapes About Sweet Ones

Xavi bought some grapes for $12. He said if he hadn't been so shocked, he would have demanded that the vendor take them back. Then he proclaimed that they were better than sex, though nothing is worth $12. I said, "Sex is." I should have specified what quality. He's still kind of irritated that they costed $12 and would prefer that they had been nasty and sour. "Having sour grapes about sour grapes - now that would have been funny."
