When you're at a chinese buffet and you get a bunch of fortune cookies, add "in bed" at the end of every fortune.
...You've never done that before? xDD I got a fortune once that just said "It tastes sweet". ... You can imagine how immature my friends and I were being about that one.
I'm not sure what's worse, the fact that I knew exactly what you're talking about or how hard I laughed. xDDD
