(Somewhere)
There was a blondie standing on one side of a river.
She's sees someone on the other side of the river (another blondie) and calls;
"How do you get to the other side?" The blondie on the other side of the river looks at her feet, then at the other blondie, then at her feet.
Finally she looks up and shouts; "You are on the other side!"
