miss piggy flub
I just bought the 50th anniversary edition DVD and watched it last night...
In the scene were miss piggy is first talking to kermit, and long john shows up. Kermit says "oh no not him too" and miss piggy saying something like "I needed commitment, I'm a WHORE, you knew that when we first met" My eyes widened and I was shocked that maybe I misheard it....
after rewinding it about a dozen times, and putting on the subtitles on, I am almost positive she said "whore" the subtitles say "pig"
I think what happened was it was a flubbed take and Frank Oz adlibed the line as a joke. They often insert adult content in mis-takes, but this time they mistakenly kept it in.
