<human>: This actually happened last year but as I was de-icing the car I remembered it.
So a sudden freeze hit where I lived and I was unprepared no de-icer, salt for the driveway etc.
 So after almost knocking myself out slipping on the ice whilst pushing my stuck car, I go down to the supermarket and load up on anything winter related: shovel for snow, de-icer, salt, liquid snow chain.
Now the next day after my shopping spree I go out to my car all frozen over and feel smug that I am now prepared. I reach into the darkness that is my boot and pull out the blue can of de-icer.  I spray my windows liberally and stand back waiting for the ice to melt...

But it doesn't, it just gets sticky... I've just sprayed liquid tyre grip over my windows, and boy its sticky. I spend the next hour trying to remove the glue/mess in the process wrecking my window wipers.
In my defence the can's are very similar:

<bot>: Went to de-ice my car window and in the darkness mistook liquid snow chain for de-icer therefore covered windows in glue.
