Some of the celebrities seen in Hell during the hukilau include Adolf Hitler, John F. Kennedy, John Kennedy Jr., Princess Diana, Zedong Mao, Gene Siskel, Jerry Garcia, Tiny Tim, Walter Matthau, George Burns, Frank Sinatra and Dean Martin. And Michael Landon in his brown little house on the prairie outfit.
Hukilau is netcasting, which is a community event in Hawaii. Fisherman cast huge nets into the sea and reel them in full of fish.
Cartman quotes Mark 9:43 in his street corner speech.
This episode focuses on the boys obsession and fear of Hell. However, Kenny has died numerous times in the past and even shown going Hell in Bigger, Longer, and Uncut (1999), plus Satan and Saddam Hussein invaded South Park in Bigger, Longer, and Uncut (1999), so Kenny would know what Hell is like already and the boys would know how laid back and merciful Satan is.
First appearance of Heidi Turner (after she was featured in the Southpark Movie), although she is called "Marcy Turner" here.
