Brock's flirting with girls was pretty good. Even if its overused like most gags, it doesn't take more than a moment to execute and balances his personality. Everybody has a weakness and his is girls XD. I also liked Corphish's eagerness to greet everyone . It's quirky and funny, but not corny or unreasonable.
edit; oh wait, one more thing. James's laugh. I dare you to not lol.
