A recently married couple went out for drinks with their neighbours, a middle-aged couple who had been married for twenty years.
Having knocked back a few, the older husband turned to the newlyweds and said with a wink: "I bet you two are like a couple of rabbits in the bedroom."
The newlyweds laughed awkwardly at this and then the young husband asked. “Well, what kind of bedroom animals are you two then?"
The older husband screwed up his face, thought, about it for a moment, then replied wryly, “Don't know about me, but Margaret here would have to be a camel – she can go for weeks and weeks without sex."
Without missing a beat, Margaret replied, “That's funny because I was thinking George here would be a camel too – two humps and it's over."
