What's in a Name?

He told me his name was "Modesto".
When I ask around about him, some give me a puzzled look. I describe him and they say, "oh, you mean Cuba". (Pronounced, "Koo-bah.)
Once I heard someone refer to him as "Tequila".
Strange, I've never known him to drink Tequila.
I always call him Modesto.
"Modesto, mi amigo, que pasa?!"
