I was in a show lineup a few years back getting an autograph, and the subject of Mays came up. The guy next to me tells a story of "I was in a lineup for Mays once when... " types, but I'll relay it back anyhow.

Some guy in a lineup had a home plate full of sig's, all done in black felt. When he brought it up to Mays, Mays grabbed a blue sharpie.
The guy asked "Mr. Mays can you please sign in black pen."
Mays: "I only sign in blue."
Guy: "Mr. Mays, can I please have it in black?"
After some back and forth, Mays grabs the black sharpie, signs his name, and then does a loop with the sharpie all over the other signatures on the guys home plate. According to buddy, he reached over the table and grabbed Mays, and security jumped in.

Years of work on his collectible were ruined.
