Heh.
I thought "false eyelashes". Then boobs. Then teeth.
Re the shrimp on the barbie thing, I always thought the point was sort of a "things are big in Aussie" thing that was going on back around the Crocodile Dundee days. Playing off "That's not a knife, THIS is a knife" and he hauls out a huge one. Shrimps are tiny, if you threw one on a barbecue grill, it'd fall right through... unless it was a huge Australian one.
Actually, I just went and found the ad since I haven't seen it in over 30 years, and sure enough that thing he holds up at the very end when he says it is quite a bit bigger than any shrimp I've ever seen.
