Not much is known about the eponymous Dr Foster- though some suggest he was Edward I, whose horse got stuck in the mud outside Gloucester.
Add this one to your collection of rhymes for a rainy day.
Sorry- tracks are only up for a week- but plenty more are on their way!
Dr Foster went to Gloucester
In a shower of rain
He stepped in a puddle, right up to his middle
And never went there again.
