How to use --expired yogurt-- ~3 months past the sell-by date? (besides eating it)

I have a quart of expired lowfat organic yogurt-- that expired in January (about 3 months ago) I do NOT want to eat it. I am not much for using facial masks, which seems to be the most common answer. And I don't have a need for the Reader's Digest suggestions I found online for moss paint and finger paint. What secrets for non-eating uses for yogurt do you have?

When we had a new extension built the builder painted on sour milk to accelerate the brickwork ageing and make it blend in with the house sooner. Sounded like a load of rubbish to me, but it might be worth a try.
