>>77940823Homer sees a gym and appears to be unable to properly pronounce it. Mild laugh: Homer is stupid.
Then Homer enters the gym and sees that it is a gym. After chuckling at his own ignorance, he knowingly identifies it as a gym. However, for whatever reason, Homer still completely mispronounces the word gym. He believes he is no longer ignorant, but he is still ignorant to an extent. A bigger laugh is generated by the absurdity of his ignorance.
