A reference to the Australian movie 'Crackerjack' (2003). The Wheel of Cheese is an item at the staid Cityside Bowling Club. It is meant to be used to make cheese and crackers...and ONLY cheese and crackers! In the film it is misused by the central character to make an actual sandwich and is used as a device to suggest the tearing down of a particular sacred cow.
Don't mess with the Wheel of Cheese.
