but...you called me

some guy called the office and i answered and said my required greetings and he was like "WHO'S THIS!?" and so i once again repeated my name and he was like "WHAT COMPANY IS THIS!" and once again i told him the company name and he was like "WHY ARE YOU CALLING ME!?" fighting back laughter i was like "no, you called me!  and who is this?" he didnt' tell me his name but he was like "you called my number and i wanted to see who was calling.  what does your company do?"  "patents and trademarks" i told him and he said "oh...no i don't know nothin bout that" and hung up...yup
