Larry Bowa made much of his reputation as a hard-nosed player from his expertise as a bench jockey. I found this in Baseball Digest, where he hassles Cincy shortstop Dave Concepcion.

“Elmer, yeah you, Emler.
“Me?”
“Elmer, isn’t your name Elmer? Every time I look at Reds box score I see E Concepcion. I thought the E stood for Elmer.”
