what does oral sex and and espionage have in common?

one slip of the tongue and your in the shit

an old couple in their 80's are sitting drinking in a bar the man says "do you remember the first time we made love?". "of course" replies his wife " 65 years ago we were sitting in this same pub and you suggested we go outside for some fun and you took me from behind over the fence it was so exciting"
"do you fancy doing it again for old times sake" asked the man
"sure" says the wife
so they head outside, a man who was sitting at a nearby table and overheard the conversation think this should be something and follows the old couple out and hides in the bushes.
the old couple approach the fence she lifts her skirt and lowers her nickers the man again enters her from behind as she leans on the fence, immediately the man begins thrusting forcefull and very energetically. they are at it for an hour and the pace doesnt let up at all, the man watching is amazed at their stamina and when they finally finish and lay on the grass to rest he goes over and explains that he overheard their conversation and had watched their romp and was amazed that after 65yrs together and at their age they could still have such great sex
to which the couple replied "65 years ago that fence wasnt electric"
