Can I Get A Happy Birfday???

ok a tribute the Patio on her 29th/50th birfday: it goes a little something like this:

Happy Birfday to you
Happy Birfday to you
You look like a monkey
And ya smell like one too!!!

Let's see, 50 years...holy cow. thats half a century old but only 5 decades. whomever said that i wasnt good in math can shut their hole. English on the other hand, i think not.
