Itchy then points to the screen, causing Scratchy to realize with horror that his Brain is now integrated into the computer. Itchy then controls Scratchy's actions by pressing the mouse buttons causing him to poke himself in the eyes in the left-right-left-left-right-left order, then begins to position his finger over the "delete" key.

Note: Because of large cutbacks at the network, the normal voice actors quit, and Krusty dubs his voice over the cartoon, sounding very uninterested (mainly due to annoyance at the fact that he has to be affected by the $10,000,000 fine from the FCC due to Kent Brockman's swearing on the air, which was the reason behind the aforementioned large cutbacks). He reckons that Itchy killed Scratchy because Scratchy was messing with [Itchy's] wife. The audience upon watching it were left gaping in shock and horror, with barely any applause.
