Pasta and plaster

My other half currently has a minor skin complaint that requires a fresh dressing every day, after showering.

The conversation went something like this:

"Could you put the pasta on?"

"But won't it get wet if I do it before you go in the shower?"

"What are you on about? Of course I won't take it into the shower"

"But you will if I put it on beforehand"

"No, I won't. Why would I take the pasta into the shower?"

Listen out for the penny dropping:

"Did you say pasta or plaster?"

You probably had to be there...
