My late night thoughts are usually not actually inane.

[Roxy and Dave have that covered.]

Generally, they trend to the obnoxiously metaphysical.

[Dave, late at night: When your lips touch do you kiss yourself?
Dirk in response: How can we ever know ourselves if the frame of study will always make its very object inaccessible?]

If you really want that kind of question late at night, then sure. That is what I'll give you.
