Books like Ketchup on Your Cornflakes?

Yeeeees! The book of my childhood, my brother and I adored putting ketchup on our cornflakes, custard in our bath, toothpaste on our head...Well, if you have to do the cleaning up afterwards, maybe this book isn't such a good idea, but although the layout is simplistic it's fun, brightly coloured and silly. My brother and I fought often over who would get to turn the pages. I picked this up again just the other day, now a teenager, and read through it with my little cousin, who thought it was hilarious. At every combination I asked her, "Do you like X on your Y?" and she would decide yes or no.She always answered yes on the rubber duck. "You always want the rubber duck!" And that night she slept well.
