I saw a Citabria do that once, just not as severe. It was enough to damage the prop and twist the drive shaft.
The pilot was showing off in the rental plane doing a 2 wheel landing like he should have then keeping the tail wheel off the tarmac as long as possible. Unfortunatly he didn't know when to stop and got the tail a little too high.

I was 17 at the time and was watching him come in while I ate lunch in the airport cafe I announced he dinged the prop and proceeded to head back to our hanger (it was our rental) as the old timers scoffed at me that I didn't know what I was talking about.

They were much nicer to the stupid kid after that day. I was a lineman for 3 years while in high school. Why I never pursued flying after that is beyond me.
