Something I found on Facebook, it was a little kind of cute phrase that goes something like this;

"Don't be sad, because sad backwards is das, und das ist nicht gut".

I was just happy I was able to understand "und das ist nicht gut" without going to google translate, and knowing what word das was translating to (das being translated to that), though I keep translating it to "and that's not good" instead of "and that is not good", "and that's not good" just sounds better in my head, I dont know why.
