Dear Doctor,

I'm writing this note to remind you to EMPTY YOUR POCKETS before sending you coat in to be washed. This morning we had to remove the following from your pockets: one bag jellybabies, one map of the London Underground (from 1940), sonic screwdriver, emergency flares, remote scanner, one copy The Time Machine by H.G. Wells, one roll of parchment paper, three fountain pens, no less than TWELVE!! Bottles of ginger beer, one bag gold dust, one note from Leonardo DaVinci, several conkers, one suspiciously fresh looking piece of celery, twelve balls of string, one jewel encrusted copy of the Rubyat of Omar Khayam, and one live hamster and three odd socks.
Not only that but I have reason to suspect that my other customers socks are getting stuck in the pockets of your coat when I put things in the dryer. I have lost five hundred and forty seven socks so far but have only recovered three.
Personally Doctor, I think it's about time you had a go at fixing the washing machine in your TARDIS.

Sincerely,
The Ladbroke Grove Laundry Shop
