Some of the jokes do land, but I think some of the larger ones would need some explanation. I don't belief you can just hook up pipes and move large amounts of how you called it "billion-dollar weapons" and no one noticed anything. (I am also not one for throwing shit at someone, I would have just hooked up the door control with the sprinklers.)
If he did these stunts the last years why wasn't he under constant observation at least a week or even 3 days in advance?
Also up unto the very last sentence I thought that there were terrible, terrible consequences coming his way (like a breach or a technical malfunction do to a security override). If he does not have some very fun loving Beta or Alpha staff he is in for a bit more than a punishment he would consider "worth it".
