I get that siren malfunctions and fails are nothing to sneeze at considering the sirens' purpose and the implications of a complete fail, but sometimes it's hilarious when sirens sound awful. What's the funniest siren fail you've seen in person or on the internet?
Personally, the funniest to me were when WarningSirensOfMichiana recorded a Whelen WS-2016 completely die internally in Woodburn, Indiana and when the old Taycheedah Wisconsin Soundmaster 115 did a silent hi-lo signal.
