Wrong Number, Please !

"Is Mike there?" I asked.
"He's in the shower," she responded.
"Please tell him his girlfriend called," I said and hung up.
When he didn't return the call, I dialed again. This time a man answered. "This is Mike," he said.
"You're not my boyfriend!" I exclaimed.
"I know," he replied. "That's what I've been trying to tell my wife for the past half-hour."
