Rude or funny?

So I have this friend... yes, it really is a friend and not me... who had his tongue pierced and then accidentally swallowed it (the post, not his tongue). Then he sends out an email saying, "suppose someone hypothetically swallows a tongue ring, could it hurt him?" LOL! Too funny. Well, that story has come up again and it is still funny! Am I rude? I think not. It's not like I was there when it happened and laughed.... I just laughed later.
