It's not that I've found this task difficult, I've just found it a little difficult. Therefore I am throwing in my 'difficult' joker card and in doing so I am using the term "greatest qualities" very loosely, after all, one persons' greatest is another persons' party trick.
(1) I'm a good person to have on your team for a music quiz. There's things I desperately want to remember but unfortunately, if it's not music related then I struggle. Always being on the winning team meant I got banned from participating by John, the Landlord from The Black Horse.
(B) I can roll a nice, tidy spliff in less than 60 seconds. It's a fact, so just Let It Be.
(iii) When playing chess, I can anticipate 24 moves ahead. If there's a wager involved then I can go up to 28 but that's about my limit. The only time I struggle is if I lose a Rook within the first 12 moves, then my game goes to pot.
(four) My feet don't smell. Now, I can see where some people would frown upon this, but let's face it, wouldn't you see that as a great quality in somebody. Especially if you had to sleep in the same room as them.
(cinque) I never fart in anybody else's presence. I think that one speaks for itself.
