I’m Gonna Kick that Ole Bucket

There's a bug in my water,
  dear Lisa, dear Lisa,
there's a bug in my water,
  dear Lisa, a bug.

Have it scrutinized, Henry,
  dear Henry, dear Henry,
have it scrutinized, Henry,
  dear Henry, please do.

It defies recognition,
  dear Lisa, dear Lisa,
it defies recognition,
  no one has a clue.

But how did you get it,
  dear Henry, dear Henry,
tell me how did you get it,
  dear Henry, say how.

It just came on the grapevine,
  dear Lisa, dear Lisa,
it just came on the grapevine,
  dear Lisa, somehow.

What is ailing you, Henry,
  dear Henry, dear Henry,
what is ailing you, Henry,
  what puckers your brow?

I fear it's killing me, Lisa,
  dear Lisa, dear Lisa,
I fear it's killing me, Lisa,
  it's killing me now.

Have some water, dear Henry,
  dear Henry, dear Henry,
have some water, dear Henry,
  and cut the to-do!

But there's a bug in my water ...

(and so on, ad infinitum –
until the bug reigns supreme)
