Bob: I brought my guitar home this weekend, and conducted an experiment on my family members. While having a conversation with one, I would surreptitiously begin playing some random notes on the guitar. Mixed in would be both the fragment of the “Pointless” riff I sent you, as well as the rather distinct opening riff to Metallica’s “Enter Sandman”. “Pointless” always provoked a comment or raised eyebrow, whereas “Enter Sandman” never did.

I’m forced to conclude that you’re now more popular than Metallica. Well done!
