contradiction
 MacFarlane notes that he was surprised they were allowed to do the pickle gag , which consisted of Stewie placing a cucumber on the sofa where Patrick 's imaginary wife is sitting , but inserting it into her imaginary vagina ( to see if it would turn into a pickle ) , but suggests that maybe broadcasting standards did not fully understand the scene . The music song by the overweight people at a funeral for a murdered obese man was only shown on the DVD version and not televised , for timing purposes , and for potential boredom to viewers . The musical composition was recorded at Fox studios on the Gary Numan stage . George W. Bush is portrayed hiding in a tree house and Brian informing by Brian of Hurricane Katrina . Bush was offered the opportunity to voice himself , but declined .

 When Brian advises Stewie to “ wait and see ” whether or not he has cancer , Stewie says “ Jim Henson had a wait and see attitude , and look what happened to him . Now we ’ ve got wrong @-@ sounding Muppets , ” a reference to Henson ’ s deadly Streptococcus pneumoniae infection that was discovered too late which led to his death in 1990 . The scene then cuts to Kermit the Frog and the Swedish Chef in a dialogue sequence , with much different voice tones . The two would later appear at the end of the show , discussing the preceding events , when Fozzie Bear walks in , and says in a deep voice ( supplied by actor Michael Clarke Duncan ) : “ Wocka wocka . Who wants to hear a funny @-@ ass joke ? ” .
