Who knew about skew lines (except 6.02*10^23)?

"A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Lines that are coplanar either intersect or are parallel, so skew lines exist only in three or more dimensions.

I'm glad I got that off my chest.

However, once you pop out of the 2D world into the third dimension, you encounter skew lines. They are REALLY sad! They have nothing in common (except for being lines). They are lines in different planes. They are not parallel. They never intersect.
