Sorry but I have to bring this up. WTF is with the slice thing? It is just as big if you cut it in to 10 slices or 2. You ask how big is it, 'oh 8 slices sir' well it just isnt 8 slices big!
This is a family annoyance. One day (btw this is a 100% true story) my dad bought a cake, and the girl behind the counter asked if he wanted it cut in to 6 or 8 slices (at which point my mum RAN out of the shop) he said back to the girl 'oooh, arhhh hmm, I think you had better just cut it in to 6 bits, as I dont think I will be able to eat 8.' She had NO idea. Poor girl.
