The Beagle Has Landed is an episode of The Itchy & Scratchy Show. Comic Book Guy later proclaimed it to be the "Worst. Episode. Ever!" and many other characters, including Bart, Lisa, Milhouse and Marge reacted negatively to it.
This episode marks the debut of Poochie. Itchy and Scratchy are in a car together on their way to the fireworks factory on the way they pass signs indicated how much further they have till they get there. On the way they run into new character Poochie (voiced by Homer Simpson) who goes on a long rap to introduce himself and illustrate how "Hip" & "Extreme" he is and also how much attitude he has (note the sunglasses) and finishes by telling children watching to always recycle to the extreme. Poochie drives past the fireworks factory.
