Episode; 'Modern Men', when Del is trying to persuade Rodney to visit Southall & Wembley and try and sell the new 'crash turban' to members of the Sikh community;
Del
"They will be buying these by the thousand. Then we'll be selling through-out Asia and America and Australia".
Rodney
"You expect me to go over and sell it?"
Del
"You are my new director of sales aren't you?"
Rodney
"They'll smash my head in!"
Don't know why but that scene just creases me up.
Also the one when they buy the blow up dolls off Dirty Barry, when Del's pretending that the doll is actually his date for the night; "Goood evening"
