The moment I saw the O RLY Hat I said to myself, " Oh boy, the YTMNDers are gonna have a field day with this one. "
O RLY owl was a HUGE fad there, and it was all based on a white owl that had the expression that just seemed to be saying " O RLY? " thus it became the symbol of O RLY.
Then they came up with another owl to be YA RLY, and then another white owl in a shocked/high expression for NO WAI!
I'll laugh if they later make a YA RLY item.
Though, it's possible it's a tribute. The original O RLY owl died some time ago.
Also, this bit for Steve Irwin:
