'Yippee!' said the trio of gremlins, as they hopped from bench to bench down the centre of the High Street, scattering humans and pigeons and seagulls alike, then leapt simultaneously onto a tree and proceeded to swing around the branches, shaking leaves and twigs and pigeon poo onto all and sundry.
'Uh?' said the gremlins, as one of the humans inexplicably turned into a big, furry, warty troll, grabbed the tree by the trunk, pulled it out of the ground by its roots, swung it round its head several times and flung it, with an enormous degree of troll-like umph, directly upwards.
'Yaaahhhhh!' said the gremlins, as the tree onto which they clung acquired escape velocity, punched through the Earth's atmosphere and continued beyond into Deep Space.
