Army pilot walking on the beach and spots trinket. Picks up trinket and give it a buff and there is a puff of a smoke and the genie of the trinket appears with the words, "I am the genie of the trinket and I will offer you three wishes.....but be warned, whomsoever you hate the most will get two of what you wish for. Who would that person be?"
"Easy, RAF pilots, I'll have £1,000,000 please."
Genie, "Certainly, but all the RAF pilots you know will get £2,000,000. What do you want next?"
Army pilot, "A 1961 Ferrari California GT please."
Genie, "Yep, but again, all the RAF pilots you know will get two of these magnificent cars. What about your final wish?"
Army pilot, "Tricky.......uhmm.....tell you what, I've always fancied donating a testicle!".
