It's true, whenever someone asks me how well my oldest daughter is doing with potty training, how my car is running, or how LSU is doing during football season (or any other similar question), if the response is a good one, I knock on the nearest piece of wood I can find, just in case. Don't want to jinx it!
The first time I ever heard of this was while watching Dumb & Dumber. It piqued my curiosity and after questioning my grandpa I learned it was an actual superstition. From then on I've always thrown salt over the shoulder after any spill.
If the clasp on your necklace slides around to the front, kiss it.
I have no idea where this one originated, but my friends and I always kissed the clasp on our necklaces whenever they turned to the front because we were told it meant the person you liked was thinking about you, and by kissing it they would be yours. Silly little superstition, but to this day still I kiss the clasp whenever I notice it in front, out of habit.
Exessive tickling will give baby a stutter
I've heard this one my entire life. Anytime someone would come visit with a new baby, there would always be one person who wanted to tickle the poor thing until it couldn't catch its breath, and either my grandmother, mother or aunt would sternly remind them, "Don't tickle that baby too much, you'll give him/her a stutter!" I always thought it was a ridiculous superstition, but once my babies were born, I found myself asking people not to tickle them too much....just in case...
