As a father, Thranduil can be a little overbearing.  Legolas constantly feels the need to be perfect and 'princely' in everything he does.  One day, while journeying about knocking off orcs for fun, he meets up with a roving group of entertainers.  

Alas!  The leading lady breaks her leg and cannot act.  (You can see where this is going, right?)  Legolas discovers there's a something perversely enjoyable about dressing up as a girl and acting on stage in the many villages of men they pass through.  Thranduil would have a fit if he ever found out!  

This goes on for many years until, one midsummer's eve, Legolas is giving a fabulous performance when who should show up but Elladan and Elrohir!

They've never met, but Legolas instantly realises who the twin peredhel are.  Legolas must make a hasty escape before he is discovered!

Unfortunately for him, the twins have seen the incredibly beautful lead 'actress' on stage and are desperate to win 'her' favour!

(Extra credit if you manage to include Elrond worrying over his sons' infatuation with a 'mortal woman')
