Haha that's amazing, as a kind of thank you how about this:

I overheard on the Bakerloo line two Transport for London employees talking about safetly and one pipes up and says "of course most of the inside of the Bakerloo line is covered in asbestos, they have to spray the inside of the line with glue every year and check the air quality - it can't ever be removed of course - as soon as you disturbed it you'd be completely fucked".

I try to avoid the Bakerloo line these days...
