I love his facial expressions, like when Liz slapped him and he kept smiling or when Jenna kissed him and he was startled and didn’t move his lips, or when he smiled and jumped up and down with Jenna, Liz and Claire but then immediately started crying. Jack McBrayer is hilarious and it was also funny when he screamed, like when he screamed, “It hurts!” after Jenna accidentally set his page jacket on fire.
