Husband & Wife.

[Monaro Pete]

The husband notices that his wife's arse is getting quite large & comments on how much it looks like a washing machine.
The wife ignores the comment & carries on.

Come bed time the husband is feeling quite amorous & grabs his wife's arse.

She pushes him away & says "I'm sorry, but I'm not switching the washing machine on for such a small load, you'll have to do it by hand".
