For the most productive 30 minutes ever!
Whilst waiting for my hair dye to do it's job I:
plucked my eyebrows and chin hairs
'immaced' my legs
dealt with the hard skin on my feet
executed a perfect pedicure
exfoliated my elbows
dealt with a skin tag
did 3 sets of squats 
bleached the loo
descaled the bathroom taps
cleaned the bastard louvre blinds in the bathroom
scrubbed sink and loo
polished the mirrors
cleaned the bathroom window
unblocked the hair from the plughole (vom)
AND scrubbed the inside of the shower panel
But that's not all!
While I was waiting for the conditioner to do it's job afterwards (10 mins), I also managed to worm and flea-treat the dog (he practically lives in our bathroom - don't ask!), clean his teeth and give his little beard a trim.
I managed to achieve a sparkly clean arse and bathroom all within 30 minutes and now need a bloody nap
