In season one, Huey was seen smiling when he defeats his brother Riley and in "The Passion of Reverend Ruckus" when he asks Jazmine to come with him to prison (though the smile is quickly replaced with anger toward Jazmine) and twice in "The Block is Hot" when he set up his soap box and when he watched Jazmine speak with Ed Wuncler Sr. In season two, he is seen smiling four times. Twice was in episode "Home Alone" when he nearly cuts Riley and at the end when Granddad returns home after his trip to Costa Rica.
