Entertainers

Some people sure know how to entertain. Take for example an interview I was watching the other day. Here is a rough transcribe:

Interviewer (Ir): BTW, you are probably the first actor to have contributed a new word to the English dictionary.
Interviewee (Ie): Really? Which word is that?
Ir: Jiggy
Ie: Wow! They put that in?
Ir: Yeah
Ie: Wow! Now, I've to look up what it really means... 'cos I have absolutely NO IDEA what it means!!!

You may have already guessed who this person is.... yes, Will Smith. Robin Williams is another such entertainer.... there sure are many more.... inputs?
