Hole in Chambers

Chambers 114 today. Two things I would like to know:

• (unrelated) Why was there a CKI general meeting yesterday. Yes, you guys said that we would probably be meeting up again, but during a 3 day weekend? Seriously?
• How can a hole be made with this size in the Chambers building? I mean someone had to make an effort in order to do this

I'm not sure whether or not someone found a hole to get through to Chambers (either physically or virtually) but either way they had it patched by Thursday morning.
