You could say I'm shaking with laughter.

Don't make jokes about Michael J. Fox.

--Not tasteless

--Borderline tasteless

--Silly, but still bad enough to warrant overall disdain

--Tasteless and frowned-upon

--Obscenely mean

>>So unexpectedly, obscenely mean I burst into laughter when it hits me.
Haters gonna laugh at sh'it they find funny.

In an attempt to find a picture of Michael J Fox facepalming, I found out there are a lot of pictures where people added gratuitous amounts of blur to pictures of him standing next to people.
