* The Christmas special
* My Friend The Smart Banana. IM Weasel crying as he helplessly watches his banana friend die.
* The end of the final episode, I Am Legend. Mainly cause it turns IM Weasel into a {{Woobie}} when he finds out that everyone loved IR Baboon and no one cared when he quit the show. Poor, poor Weasel.
* The scene in the Pixie-Fairy episode where the Weasel pixie dies in Weasel's hand.
* That time Weasel succumbed to his [[GRatedDrug egg addiction]].
-->''"I have lost my humanity!"''
* In "I.R.. Wild Baboon" Weasel is sent to life in prison for illegally pushing Baboon in his trailer down a waterfall. He tells his story to the Red Guy as a news journalist hoping everyone will know the truth, but he's been asleep the whole time and hasn't written anything down. Weasel ends up back in solitary. Then, [[CatapultNightmare Cow wakes up]], [[AllJustADream having another one of her "bad weasel dreams"]].
