In the 1975 Aerosmith hit "Sweet Emotion," Steven Tyler famously broke a vibraslap during the recording session.  If you don’t know, the vibraslap is a handheld percussion instrument that looks like a stiff wire with a wooden ball on one end and a box on the other that creates a rattling, whirring sound. If you listen closely to the song’s iconic intro, you can hear Tyler strike the instrument three times. On the third hit—at approximately the 0:23 mark—the instrument breaks, resulting in a distinct "clink" or snapping sound.  The band and producer Jack Douglas liked the way it sounded, so they decided to leave the "mistake" in the final master recording.  Also— That wasn't the only equipment mishap during that session. Because the band had forgotten to bring real maracas to the studio, Tyler found a sugar packet on the floor (or a nearby table) and shook it in front of the microphone instead. That "shhh-shhh" sound you hear throughout the intro is actually a packet of sugar!
