YOUR GIRLFRIEND/WIFE AND YOU WILL MAKE LOVE 26.22 TIMES IN ONE NIGHT. THAT’S ROUGHLY 3.3 TIMES PER HOUR, FOR 8-HOURS… THAT WAY, IF YOU GO TO BED AT 10 PM, YOU CAN FINISH AND YET STILL GET ENOUGH SLEEP TO BE PRODUCTIVE THE NEXT-DAY (PREFERABLY A SATURDAY OR SUNDAY). HOORAY! HOWEVER, YOU'RE GOING TO NEED A MINI-FRIDGE, TWO-PLASTIC GLASSES, FOUR-ENERGY DRINKS, SIX-BOTTLED WATERS, THREE-GALLONS OF ORANGE JUICE, 10-MINI BOTTLES OF KY (SUFFICIENT LUBE), AND 2-3 SUB-PAR MOVIES; BECAUSE IF THEY PROVE TOO INTERESTING, YOU AND/OR YOUR LOVER COULD POSSIBLY GET SIDE-TRACKED, COSTING YOU PRECIOUS TIME. THIS TIME SHALL BE CALLED, “MARATHON”.
"Tina and I will hopefully entertain thoughts of "Marathon" tonight. I accidentally left my seeing glasses at the office during lunch and ingested 4-Viagra pills by mistake. Things aren't looking good down below. So I figure I will mention it at dinner and see how she takes to the idea."

A marathon is a long distance race of about 42 kilometers. The marathon was created in honor of the Ancient Greek messenger Pheidippides, who ran the distance from the Battle of Marathon to Athens and then collapsed.
I've run almost every marathon in the world.
