Decades ago, as part of the CalTech freshman experience (Page House), I was required to buy a set of lock picks, learn their use and pick three designated locks within a time limit. Penalty for failure was being tossed in the showers by sophomores.

This was handy for getting around the Institute after hours (steam tunnels).

You would probably be sad to know that the steam tunnels are no longer accessible to students at will and South Masters are passing out of the living memory of students (the last time they could be used was in 2010-11)
