You can't have a "Brain Teasers and Riddles!" thread without Albert Einstein's famous riddle. Without further adieu... I will provide thread followers with brain teasers and riddles routinely. I will seperate them into three different categories: Easy, Moderate, and Advanced riddles. Also, please don't search for answers on the internet! Use your brain power. I know this thread will have a lot of spoilers so read with caution!
