THREE  RHYMING RIDDLES

1)
I've got a lot of keys, eighty-eight to be exact;
And not a single keyhole, and that's a fact.

2)
Though awkward may be your first,
More of me will you  thirst;
And though more of me you will get,
Your first you will  never forget. 

3)
I know what my job is,
The point has been made;
You may say I have a big head,
And you're right, I'm afraid.
Put me in my place,
And then leave me alone;
What I need most
Is someone to drive me home.
