I remember in the Sega Genesis version of Home Alone, if you used finished off the crooks Harry and Marv with the Electro Magnet gun in the Old House (which was falling apart and had weird music to begin with), the finishing cut scene would become scrambled with a horrifically loud buzzing sound and would just freeze. It's crazy how distinctly I remember this, because it used to TERRIFY me as a kid when I played it.

Looking back today, I'd probably be like... eh, whatever.
