Simpsons, The Easter Egg - Crocodile Dundee References

There are 2 Crocodile Dundee references in the episodes, the one where they're in Australia, and the one where Bart joins the Boy Scouts.
Aussie Episode: When Bart's playing with the pocket knife in the bar, a man (looks like Indiana Jones) comes up and says, "That's not a knife, THIS is a knife" which is a line said in the Crocodile Dundee movie number 1 (also the look gives it away)
Boy Scouts: When Huns Moleman is kicked out of the bar, and Moe threatens him with the knife, he then says the same quote mentioned earlier, and with the same style knife as Mick Dundee has in the movie.
