Enjoyables.

This video never fails to make me laugh. I feel like I've done enough PCR to last twelve thousand scientific lifetimes, but I don't think I've ever reacted like the guy who kisses the thermal cycler.

This response is relatively new and almost as funny, though I don't have the same emotional attachment to the product. Enjoy.

And today's xkcd is perfect for me and my copyediting psychosis.
