What?

This is Mars. He is a young chap who really likes a drink. In his case it is goats milk of course. So he was a little perplexed at the sudden appearance of this bit of advice on easel and canvas in his field today.

This will be my WBC entry for 'Canvas' as I couldn't find any blank ones. Went for the odd rather that artistic option this week. Kid two weeks in a row. I'd better go for something different next time.
