Cheap Trick got me out of detention...
In high school (like 2003-ish) I got detention for skipping class (or being chronically late to class, i forget). The person who ran detention was this big, no-nonsense dude who, rumor had it, was a former drug dealer turned school security employee. He was also really into all kinds of music, mostly rap and hip hop, but also classic rock.
He'd play music in the classroom while you sat in detention, and about 5 minutes into detention a song plays on the radio, and he's getting really into the drumming. He calls out, "anyone knows who this is?" and nobody answers until I say, "Cheap Trick, I Want You to Want me (Live at Budokan)." He said to me, you're free to go.
Who knew knowing classic rock would get me out of detention early? A big reason I knew that was not because I was into them, but because that song would always play on the classic rock station my dad listened to on his commute home.
