What's the most you've ever lost while trying to clear a bonus?

[DrewOnTilt]

I'm working on clearing the $150 Empire bonus at $0.50-$1. If Empire was to magically release my bonus right now, I would have made a whopping $9.98. 70BB downswing in just over 600 hands. YIKES! This has been a run of 2nd best hands the likes of which I had only read about up until now. I'm just glad that it is happening on somebody else's money.

I'm curious to know as to what is the worst others have done while clearing a bonus?
