I remember one time I was playing one of those video game manifestations of the Lord of the Rings franchise, Two Thrones I think it was. Anyway, there was this bit where you had to fight the troll in the scene where the heroes get attacked in the burial chamber in Moria.
I swear to god I got so pissed I tore the disc out of the console, snapped it in half, and gave my friend $50 to go buy a new copy because I borrowed it from him and I forgot that with my mind in a fog after being killed by the troll for the 17th time.
