I remember when we used to be able to get Lucky Charms like regular cereal. Now it costs like seven bastard pounds for a little thin box, and you can only get them from stupid uber-cool shops for rich idiots.
As for the favourite cereal, then good old fashioned wheetabix smoothered in sugar with nice cold milks is always good to wake me up before an exam. Aside from that Wheetos, Chocolate crunch nut and chocolate/frosted shreddies are always good. Though the latter always make my stomach feel real weird a while after I've eaten them. Frosites are the best to just eat out of the box. Hurrah for cereal says I.
