tears downhill full tilt
Professor Percy Postlewaite perched on his penny farthing preens and poses. Proceeds precariously past "Patterson's Pies" and the Co-Op. Pedals, puffing, panting, puffing, panting, perspiring profusely to the peak of Primrose Hill. Teeters, totters, can't touch down a toe to go slow but tears downhill full tilt on tinpot wheels. Ter-ump, ter-ump, ter-ump over the cobbles, the kerb; pelts through the portals of Prince's Park, presses a bed of purple pansies flat. Look, mama, lisps little Lizzie Lumpkin. Look at Pwofethor Pofflewaite paddling in the pond!
