'Ons' are what physicists are all about. Neutrons are novices in the field. Protons are those in favour of having physicists within the scientific community. Bosons are rather bombastic physicists and are sometimes referred to as Mesons. Gluons are physicists who will not change their outlook regardless of experimental results. Gravitons are the most serious of all physicists whilst Photons have a much lighter outlook. Anoraks on the other hand are simply seen as the hoods of the scientific community.
Trust me to forget! Dunx's statement was correct. An addition, though; Muons are not only those physicists from the family feline but also that of the seagulls. Quarks, whilst not quite fitting into this group, are nevertheless are duck-like, sometimes they are up or down (i.e. at the top or the bottom) and can be strange or charming. Odd that.
Bare back rides are much safer than Bear back rides! If unsure which is which, stop and ask a friendly Mountie (mounty???), never trust the word of a Grizzly they are compulisve liars, and have bad breath and poor taste when it comes to home furniture!!!!
