Does any one remember the Brady Bunch episode?

where they said something was L7??? I think it was a movie producer when they were going to do the Laundry soap caommercial, but I am not sure. my friends think I am nuts and dont know what L7 means. I guess I am a big square huh???

a big square? lol! I get it!

(L:-7 means square (put your left fingers to form the letter L, then your right fingers to form the number 7. put them up against each other and you have a square).

Best I can do is come up with the name and year of the episode. Can't find any transcripts though.

And Now, A Word From Our Sponsor (1971) (ep 58)

I have watched brady bunch so many times and I was born in 1964. I have all the DVD's and know which episode that you are talking about, but don't remember L7. Now, I guess I will have to watch all the DVD's because this will bother me. Thanks for giving me something to do this weekend.

sorry i don't know but a star for you because it puzzled me a little
