Probably heard this one before but it is a fact universally acknowledged that a young man in possession of a large valuable collection of vintage farm machinery is in want of a wife... said young man met the girl of his dreams and fell head over heels.
But she let out one evening that she didn't like or understand the appeal of tractors and any man who professed such an interest would be given the old heave-ho. You or I might think that the sensible response would be to ditch the bossy cow and return to the tractor shed but not our hero. He sadly auctions off his entire collection and divests his home of all tractor memorabilia, turning instead to cycling as a new passion.
With some of the proceeds he books a table at the finest local eatery for himself and his young lady, purchases a large diamond and prepares to pop the question.
Halfway through the main course, however, there is a small fire in the kitchens. The fire is put out, but the restaurant is filled with smoke and it is suggested that the diners should leave.
Not to be undone, our hero basically walks round the premises, expands his chest and breathes in all of the noxious smoke, before going outside & huffing it out into the open air. He repeats this many times until the air in the restaurant is pure again.
He returns to the table to a round of applause from the assembled diners. His intended is amazed. "How did you manage that ?"she says "what an amazing lung capacity !"
"It's OK" he replies, "I'm an ex-tractor fan"...
