I remember "Barry - you've got browno for brains"

Can't remember the chocolate one but how about when they were tasked with advertising a Viagra type product and Brent says he's had barry personally testing it for the last month.

Manufacturer rep "And you haven't experienced any side effects?"

Barry "Side effects - what side effects?"

rep "Oh they are so rare its barely worth mentioning"

Barry "WHAT SIDE EFFECTS!"

Rep "Well... we have had very, very isolated incidents of it, ah, turning green and, ah, falling off"

Brent "See barry, barely anything"
