As a child, I was sitting in a dentist's chair

And you're sitting in some messed up dentist's chair

to every patient who sits in his dentist's chair.

Looks like a dentist chair on steroids.

and I'm a tenured professor sitting in a beanbag chair.

Please, sit in the chair.

It's like being in a dentist's chair.

Sit down. Have a chair.

I'll sit right over there in the dentist's chair and we'll get started.

Just like a dentist's chair.

A real professional dentist chair.

Sit in the chair, buddy. Sit in the chair. Sit down, sit.

...who's sitting in a chair!

sit down in a chair.

Look, when I woke up, I was in a dentist chair,

She was sitting right there in that chair.
