A childhood belief about birds

others believed things like this
- i thought that "aromatic" duck was actually "asthmatic" duck.
poor thing...— rachael - I always thought that duck sauce (from chinese restaurants) was duck poop.
— emily - I believed that linguini was made of tape worms and was scared to eat pasta for a long time!— Mojo!
- I thought the “rec” button on tape recorders said wreck and it would wreck your tape if you pushed it!— Alberto Richardson
- Whenever I was upstairs on a bus, I didn't believe that it would fit under the bridge so I used to duck. — Dave, Lancashire
- I used to belive that if I didn't duck when going under bridges they would hit me.Anon
