Batman versus Superman

Here is a joke I came across about a man who is actually named Batman. This telephone conversation is between Batman and the person whom he is speaking to.

Thank you for calling, this is BATMAN
“Who am I speaking to? …”
“Batman …”

“May I have your name again please?”
“My name is Bat-man …”

“Trying to be funny huh?! What is your surname? ..”
“Supar-man…”

“I want to speak with your manager… !”
