We then carted these toys to the hospital and yesterday, we played Santa in the kids' ward. From one week to 12 years of age, every child in the ward received a toy and the looks on their faces were priceless. Some of them were too young to realise what was going on but their parents' faces said it all.
You can contribute to the appeal at any Countdown store and know that the money you are giving will be gratefully received by the staff at the hospital and well used by the kids.
Meanwhile, Sarah should really learn to keep her mouth shut.
What started as a silly little idea has now grown into a fully-fledged challenge; in just over a week's time, Sarah (who is beat deaf and quite likely tone deaf) will sing in Martin's very own Dad Band.
While the performance will be private, it will be recorded and videoed for playback on the radio and website. Gulp.
Best you get yourself some lemon tea and singing lessons, Sarah - you're going to need all the help you can get!
