Torte

A type of cake, usually multilayered, and filled with whipped cream, buttercreams, mousses, jams, or fruits. It may be glazed and garnished, and in any case is very bad for you. It does many undesirable things to your waistline, but it won't make it contract.

This gag comes to you direct from our “here all week, folks!” store of corking one-liners.

Ohhhh - did you mean tort?
