Commenting your code is usually a way to provide some background to or explanation of complicated code, most often for another programmer who's looking it over. Ruby uses the sharp (#) as a way to identify the beginning of a a single-line comment and even though the interpreter for all practical purposes ignores the information on the line, anyone reading over the code should not.
Sometimes even if the code is comprehensible, it's worth taking a look at the comments merely for the amusement factor, because not everybody uses comments the same way. In fact, I've seen some pretty unusual things added to code as "comments" now and again. Do you use the comment line in the standard manner? Have you seen some odd comment lines in other people's code? We're collecting the answers, so share with us:
