The Extranormal Institute is a strange and/or wonderful place where bizarre is the new normal. It makes good internal sense (as opposed to farce played for laughs) and is genuinely functional (as opposed to a Crapsack World or the like), but has a very high weirdness level as real people deal with fantastical things. Such a location is usually an important part of the attraction of whatever series it's featured in. Naive Newcomers (perhaps Strangers In A Strange School) can be expected to drop their eyes. The regulars may well be aware of their madhouse status and even proud of it.
