Well I am not going bum sniffing to find out
CWMBO is an expert on bum sniffing, I shall ask her

If she could talk, she would say....."hhhmmm, twiglets.......smells like bum"
Our CWMBO refuses to accept he has a bum, every time something bad happens from "there", he sits up and stares at us like we just did something nasty.

. (sometimes it is Apey though in fairness...)
