LOL that is one of the best fridge functions! But joking apart can you think what Ankur might be referring to here? May be there's some word that sounds a bit like fridge which can be applied to functions.

A fridge function is where you actually get a beer out of the fridge A virtual function is where you sit thinking of drinking a beer

Well I've been using C# since the first beta a dozen or so years ago and I've never heard of a fridge function! Googling it has also yielded a blank. However a virtual function (or method as they usually called in C#) is a function which can be overridden in sub-classes which want to provide their own implementation of it. At runtime the actual type of the object (not necessarily its compile-time type) determines which version of the virtual method to call. For example if SomeMethod is a virtual function of the Parent class which is over-ridden in the Child sub-class: Parent p = new Parent(); p.SomeMethod(); // calls Parent's version p = new Child(); p.SomeMethod(); // calls Child's version because 'p' refers to a Child object not a Parent object
