Two couples went together camping. One night one of the guys came up with an idea:
“What would you say if we swapped partners for tonight?”
The other one after thinking hard:
“Well … err … OK.”
Next morning, same guys chatting:
“I loved it!! So, what do you think?!”
“Me too, great … Now let’s go and see how did the girls go …?!”

Firefighter goes home and tells his wife about the new signaling system they have at work:
“When the bell rings once, we all put on the protective gear and the helmets. Two rings – going to the car park, and three rings – get in the truck and we’re going to put out the fire. Let’s implement a similar system at home. One ring – you undress, two rings – jump into bed, three – start with the foreplay and making love!”
She agrees. A few days later he comes home from work:
“One ring!”
She gets undressed.
“Two rings!”
She jumps into bed.
“Three rings!”
They started making love. After a while, she screams:
“Four rings!”
“???”
“Please, extend the hose – it is not reaching the fire!”
