Virgin isn't necessarily a sexual reference... get your mind out of the gutter people. Virgin has more than one definition.... THINK VIRGIN OLIVE OIL ALSO back on topic, my mom saw me listening to them and she was like "Oh is this your brother's music?" (FYI my brother is a PILOT... xD)
THIS JOKE IS NOT FUNNY AT ALL! there are clearly 4 pilots, not 21. Therefore, the joke makes no sense.
