OK, at 63, the ponytail stays because how many men my age still have a full head of hair? I'm showing off!
In re t-shirts. The Darth Vader "I am your father" one and the one on which pictures of Hulk, Iron Man, Spider-Man and Thor illustrate that Dad is incredible, invincible, amazing and mighty were both Father's Day presents from my daughter and I wear them with pride! The Dangermouse, Trap Door, StarFleet Academy and Batman ones are iconic, so I'll always wear them.
Now, where can I get one that says Cthulhu fhtagn and a Devil May Cry one?
