Dentist!!

Monica is at the dentist. Half of her mouth is locked due to anesthesia, the dentist is intensively working. Monica's mobile phone starts ringing. 

Ignoring it four times, the dentist finally answers the phone pissed:

What's up?

What's up?,  some man asks.

Dentist:

Who are you?

I'm Monica's husband

Dentist: Listen, man, I'm about to finish, she will spit it out and will call you back!!!
