Always wondered about this. Interesting.

interesting to see what Chad did after Big Brother...

LT you are funny but anything chad does gets no reaction not even a yawn :joker:

Anything bb makes me yawn nowadays.

I yawned constantly whilst reading the article and also now writing about it.
Fascinates me when people manage not to yawn when they see others yawning.
Cold hearted psycho.:laugh:

I yawned just from reading the title of this thread.
