Joe, an older gent in his 70’s had just left the social club he belonged to after an evening of drinks and playing poker. As he passed by a nearby motel, he saw a young woman dressed in a thigh high miniskirt and four inch heels standing in the doorway of one of the units.  
“Hey honey” she called out “Do you want to have some fun?” Joe replied “I can’t.” “Wait a minute.” the gal interrupted as she stepped out towards him “Honey, from what I see, you look pretty fit and virile to me.” Joe said “Thanks, but I can’t.” At that point the gal came up to Joe, threw her arms around him and began kissing him while rubbing her body against his. Joe blurted out “You don’t understand, I can’t…..” The gal cut him off, saying “Not another word, you’re coming with me.” In a daze, Joe found himself in her room, and before he could say anything, she had pulled down his pants and was giving him a lusty blowjob. As Joe opened his mouth to speak, she put her hand over his mouth and repeated firmly “I said not another word!” Before he knew it they were both buck ass naked and she was riding him as if there was no tomorrow.  
Finally Joe erupted and the gal looked down at him and said “Wow honey, that was quite a session. I don’t know what you meant when you said ‘I can’t’?”
Joe gazed at her and slowly said “What I was trying to tell you is that I can’t pay you because I have no money. I lost it all playing poker.”

The moral of the story is you shouldn’t interrupt people. Let them finish their sentences.
