Role in The Simpsons
When the Simpsons see Ned just got a new RV the Simpsons decide to get one and go to Bob's Roundup RVs. The Simpsons then see a huge RV named Ultimate Beehemoth and Homer tries to get it but brings sales down so much the Simpsons have to get a cheaper one. In Bart Gets an F, he is seen singing in the snow between Homer and Marge and Jasper.
