O Oliveo, Oliveo, wherefore art thou Oliveo?

Deny thy other olives and refuse they name as a vegetable.

Or if though wilt not, be but sworn to my hammy love.

And I'll no longer be a pig.

'Tis but thy name as a vegetable that is my enemy: for it keeps us from being together. 

Meat lovers or vegetarian pizzas are from other worlds.

But what's in a name? That which we call a cheese stuffed crust.

By any other name would smell as delicious.
