In my humble opinion there is nothing funny about disasters and people dying .
Wow, I feel like I just went to my high school reunion and my toupee fell off. (that would be "embarassed")
Henry - I thought there was a statute of limitations on disaster grief. Like 100 years or so.
Anyway - if you think about it, at least some of these jokes are more of an homage; like "It's still better than Carnival" (or insert your own cruise line there). Or "whats the difference between this place and the Titanic - the Titanic had music".
Besides that, Mrs. Lincoln, how was the play?
