Oliver is irritated to be sharing his birthday with Arnold Ziffel, partially because the pig is getting so much attention. Even after Haney pitches him on a selection of ridiculous gifts, he refuses to buy Arnold a present. This proves embarrassing when the Ziffel "boy" gives him an electric snout warmer. Even though he requested no celebration, Oliver's convinced that Lisa is throwing a surprise party, so he puts on his tux and goes all around Hooterville looking for it. He gets a surprise, but it's not a party.
