Literal “I bet chewing gum could fix that” situation. Was driving my Camaro from Ohio to DC, just got on the PA turnpike when it started raining. Turn the wipers on and the left one does a weird flip and started flopping around barely holding on. Pulled over and noticed the little clip where it attaches to the arm had snapped. Went back into the car, got some some gum from the center console, chewed for a minute, stuck it on. Wiper worked flawlessly for the next 4 hours of constant rain. I almost didn’t want to replace the wiper when I got home because I was so proud.
