My own little 'WOT' story:
early 70's, 1971 Super Beetle, middle of icy winter in Michigan, around 11:00 pm. Around 40-45 mph on a two lane. I take my foot off the accelerator to slow down, and.......no slow down, keeps on going! I push on the brake....no slow down! I look down at the accelerator pedal and it is down by the floor boards. The linkage is frozen. I grab the ice scraper (used to scrape ice on the inside of the car cabin) and try to hook it around the accelerator pedal to pull it up.....no results. I then think to myself....'sheeeeeshhh'. To the best of my recollection I downshift, and realize thats not good, then shift into neutral (clutch pedal still free), engine at high rev's, slow down to stop the car, turn engine off, work the accelerator linkage to free it up, then go home in time to watch Johnny Carson.
