OK, so I've asked loads of people about this, and it seems to be about 50/50 on people that have no idea what I'm going on about, and those that do but can't remember where it's from....
Can anyone stop me and the other half driving each other mad trying to think what it is....?
There is a scene in a TV show or film where someone cuts a piece of cake from this magnificent cake when they shouldn't,and eats it. They then pack the gap with a load of stuff, and put toothpaste all over it to look like the frosting / icing to hide the fact that they've scoffed a piece.
You won't believe how much time we have devoted to finding out the answer to this totally pointless thing, but you would be helping me put us out of our misery if you know what it was :)
