I get the door open just enough for the guy to stick his head through.

At one point I almost had to stick my head out the window.

And then another stuck its head up to the right of the first one.

A man stuck his head in and looked around the waiting room.

The door came open and he stuck his head inside.

She didn't come into the office but rather just stuck her head around the door.

The door to my room opened and he stuck his head in.

If you want, I'll stick my head in the water and look.

I quickly walked to the door and stuck my head outside.

One of the girls stuck her head into the room.
