I'm pretty sure that in the old victorian days that "laugh" was slang for a woman's orgasm. I think it's an accidental double entendre in this case though.
I'd prefer they left the gags in, they're little eater eggs that are fun for the fans. It's not a deal breaker they are removed. It's not like we can't look them up on an "Internet" or something. :P I wonder if the box stores will get this? I was going to grab it tomorrow night on the way home.
