How do you react to someone dialing the wrong number?

"Yes, yes this is Matthew."
"What are you wearing?"
"Is it sexy?"
"Oh you are di-"

I cut that off because they've normally hung up by then.

It would be more awesome if you weren't lying about it.

I tell them they have the wrong number.

One time, I got a few texts from a number I was not familiar. I called the person to inform them to stop sending texts to me, as this was the wrong number. I got yelled at about being an asshole.
