Cheers!

So far you got 91, 94, 95, 99 and 98,
While She got 92, 86, 90, 87 and 88,
I got 96, 100, 100, 97 and 84,
...why everyone looking at me for?

Since one of my exam scored 84, the lowest one...
Is that mean I am buying pizza for everyone?
But wait a minute, wait a minute...
Not so fast, let settle this...you two sit!

I don't recall making such ridiculous bet?
Both of you made decision without me in it,
Funny, very funny! But I have to admit the idea, I like it!
So, after the finals we all meet and find a place for us to celebrate...
