 " Crippled Summer " served as a parody of Intervention , the A & E Network documentary series about people struggling with various addictions . Throughout the episode , information about Towelie 's drug addiction is presented on completely black screens with white letters . This device is used frequently in Intervention . The interviews with Towelie 's friends and footage of their pleas to get help are also characteristic of the reality series . During one of Towelie 's interviews , he quotes " feels like I 'm walking on sunshine " after huffing air duster cans . Both the quote and his actions are from Season 5 , episode 9 of the TV reality series Intervention where they interview " Allison " . Many of the campers at Lake Tardicaca are parodies of characters from the cartoon series Looney Tunes . Nathan and Mimsy , in particular , are strongly influenced by Rocky and Mugsy , with Nathan taking on the role of the diminutive mastermind ( like Rocky ) who is constantly thwarted by his large but dim @-@ witted accomplice ( like Mugsy ) . Other characters from the summer camp in the episode resemble cartoon characters such as Elmer Fudd , Pete Puma , Droopy , Porky Pig , Taz , Foghorn Leghorn , and Beaky Buzzard .
