On its way into Manchester the 143 can be caught by anyone and therefore people who wouldn't get the 143 back would get it there. On its way back from Manchester it runs the same route as the 142 bus but only as far as the Palatine Road variety. Then it goes down Palatine at which point people realise they are are on a 143 and can lead many people from the Didsbury division of the Wilmslow Road variety have to catch another bus or walk home.
Nobody knows where the 143 travels to out of Manchester as nobody has ever got the bus for that purpose thus causing a pandemonium outside Job Centre Plus which would look like good evidence against unemployment rates. It is rumoured to be travelling back to the treacherous swamp from wence it was born.
Swann: "No, it's a 143"
"Ahhh fuck we got on a 143!"
"Shit, it's 5am and there's no buses we might have to actually catch a 143 instead of waiting for the 142"
One letter in I,
Four in Love,
and three in You.
Musiq made a song about it.
Of things that you really really mean to say
So I wanna out this time to make sure that how I really feel
Gets through to you
There aren’t many more ways and words that I can say
So I choose to tell you how I feel in a numerical way
Got so tired of trying to find the most complicated way
To say it to you so I simplified and broke it down
To 143 – and that means I love you
