MacFarlane is comparing Cho to Korean singer “Psy,” the man responsible the viral “Gangnam Style” video:

Cho’s comedy may be vulgar, but that’s no excuse to attack her looks. It’s unclear whether MacFarlane is suggesting that Cho resembles a Korean man or that all Asians look alike. In either case, MacFarlane’s tweet is disgraceful, and it’s certainly unbecoming of an Academy Awards host.
