Leper to prostitute: "You can keep the tip."
Lyrics to "I Palindrome I" come to mind; starts with:
Someday mother will die and I'll get the money;
Mom leans down and says "my sentiments, exactly";
You son of a bitch, I palindrome I (etc)
Seeing tons of palindromes everywhere. A full circle seems palindromic – ending and beginning are the same, and "the middle is the middle".
