Get the Megadeth mug.
Definitive state-of-the-art Heavy Metal band. Created to mock Metallica. A task they excelled at.
Enjoyed glory in the late 80s and early 90s. Now sadly turned into a bored, heavily-merchandised,
mega-nostalgia-regurgitation machine. Megadeth is infamously headed by the excruciatingly haughty
born-again Christian, Dave Mustaine. A man who rivals Kilroy Silk for foot-in-mouth antics.
"It's time for snapping some neck! Slashing, thrashing to Megadeth!"

1. Band known for their lead singer Dave Mustaine who sounds like he has nasal blockage when he sings. Also he was kicked out of Metallica for generally being an ass.

2. Not as good as Metallica
