The ad for vacationing on the Russian space station MIR...
"Lose weight in Zero G! And watch your legs and arms melt away through the miracle of atrophy!"
"Dining? The finest in tube paste food! Served in your room because there's no place else to go!"
"And all you can eat because it won't be much! Monogrammed space-sickness doggy-bags at no extra cost!"
"And speaking of cost, reserve now at your introductory rate of only $40 million! Or make an offer on Priceline.com."
"Wish your vacations could last a little longer? With MIR you never know!" A voice from earth, "How do get them down?"
