A wave of spontaneous combustion is sweeping through South Park, and the mayor charges Stan's father (a geologist) with finding the cause. After working feverishly on the problem, he finds the answer: people are holding in their farts for so long, they're bursting into flame. A grateful nation loosens its sphincters in relief, but their problems aren't over yet. Meanwhile, the boys crucify Cartman in the hopes of helping Kyle's father get an erection.

Funny episode!
22 October 2008 | by (Canada(Montreal,Quebec)) – See all my reviews

Spontaneous Combustion is a very funny and interesting South Park episode.It shows another example of how young children do not understand things and try to help but they are all wrong.Kyle's dad cannot get an erection and that's why his parents keep arguing.The boys try to find an erection for Kyle's dad and they misinterpret "resurrection" for erection after Father Maxi tells them they should preform the resurrection of Jesus Christ in a play.They hang Cartman up on a cross so he can get an "erection" and give it to Kyle's dad.Meanwhile, everybody in South Park starts "Spontaneously Combusting" and it's up to Randy to find out the solution(even though he is a geologist).He finds that not holding in farts will keep people from combusting, however the excessive farts cause damage to the air.Everybody is now angry at Randy because they do not know how to stay alive! This is a funny and interesting South Park episode.
