Gentleman Cho'gath creates champagne bottles instead of spikes

Cho'gath's Q and E abilities produce spikes, either from the ground or from himself. Even with the Gentleman skin, he still creates spikes. But why not something more gentlemanly? Why not champagne bottles? After killing his worst enemy he can sit down with him and have a nice chat over a bottle of champagne. It's a simple idea, so i don't know why anyone thought of it before.
