lyrics

I wet the bed. What's the matter?

I wet the bed. What's the matter?

Didn't you wet the bed when you were a child?

Hum ignore you.

I wet the bed. What's the matter?

Besides, you can wash it off for me tomorrow.

Isn't that enough?

Hum ignore you.

I wet the bed. What's the matter?

I wet the bed. What's the matter?

I wet the bed. What's the matter?

I wet the bed. What's the matter?

Didn't you wet the bed when you were a child?

Hum ignore you.
