Back in the day when Naxx wasnt on live servers yet, i went to Naxx on the test realm to try out some of the new content.

One bug that we found out was that there was a Hole that people could get stuck in.

After about 10 or so people got stuck in it, we found out that a GM had been watching us the whole time, and he had spawned a crazy basalisk to help us out=D.
