I just read about a Harvard psychology study where someone asked if they could cut in front of the queue at a library copy machine:

* If the cutter asked without giving a reason, they succeeded 60% of the time.

* If the cutter gave a legitimate reason like "I'm late for class", they succeeded 90% of the time.

* If the cutter gave a lame excuse like "I need to make copies", they still succeeded 90% of the time!

So "because reasons" is not necessarily any worse an excuse than any other.
