S1·E56 Are You a Traitor? / Is This a Job for Men?

Hilda notes that Oga and his friends are acting funny and that they're scheming something bad. Oga and Beel deny this, but do so in such a poor manner that Hilda easily notices they're lying. After Oga introduces the next episode, Hilda begins to think of a new dance for Baby Beel in place of the Pudding Pudding dance. Oga responds with a fake laugh.
