Always be sure before you ask.

A gentleman staying at the Ritz Hotel in London removes a card offering sexual services from a telephone box on Piccadilly. Back at the hotel he rings the number. A lady with a silky soft voice answers and asks if she can be of assistance.

The gentleman says, "I'd like a blow job, some missionary work, a little doggie-style, some mild bondage, finishing off with a pearl necklace. What do you think?"
The lady says, "I think it sounds intriguing, sir, but you might like to press 9 first to get an outside line."

"Dammit, lady, I didn't ask for technical service! I asked for sexual service!"

The operator is free, who needs the outside line?

Also this joke only works if the year is pre-1950, old man.
