Well if you've ever seen Weekend at Berney's you would already know that. If you need results from DNA or trace they will never finish unless you bring Grissom into the room, at which point the results will print immediately. If you need a brilliant idea, simply put your hands on your hips and stare directly into the sun until it comes to you.
Be careful when spending the night with a callgirl, b/c you never know if she'll end up dead the next day...and *your* DNA is all over the place, so your suspect #1
