Some know it all, while some act dumb.
Let the bass line strum to the bang of the drum.
Some can swim, while some will sink;
and some will find their minds and think

This place sure is becoming less enjoyable by the day... \ If you believe there is a question on the main site that absolutely needs my eyes/expertise(?), try pinging me in the chatroom.
