I'm sad no one got my pun. But now I shall explain it and therefore ruin it:
"There's something about a Woot! shirt and a penguin that gives me a warm fuzzy feeling inside"
This was at first glance supposed to appear like some nostalgia for the early days of Woot! and the number of penguin shirts prevalent at the time, and the eventual banning of all penguin related flying activities.
The second meaning was "warm fuzzy feeling inside" which implied that I had a penguin inside my body just like in the shirt.
Yes, it's ruined now, but at least you understand.
