I think one of the things from Pandaria he’ll never forget is being constantly terrorized by Pandaren cubs.
From his sword being stolen and being forced to play with them, to them trying to feed him all the time because they thought he’s sick and thus needs to eat more because obviously, food makes everything better. I’m also sure at least a few girls had a crush on him.
The fact that Zul’dar and the rest found it hilarious and not once tried to shoo the kids away probably made it worse.
