A fun little mnemonic to remember the standard tuning for a guitar.

From highest pitch to lowest, the strings are tuned as such:

     E  B  G  D  A  E
     v  o  e  r  t  l
     e  d  t  u     e
     r  y  s  n     c
     y        k     t
                    i
                    o
                    n

Although kinda silly, it really does help me remember what to tune the guitar to. And usually gets a laugh out of non-musicians. Three cheers for effective mnemonics!
