Just watched "Big, Bigger, Biggest" on Five, and as the credits rolled and the final shots of the Oita Stadium were shown, the voiceover girl who talks about whats on next comes out with "Wow, they're phallic aren't they..." and carries on as normal about what's on next.
Nothing in the pictures was phallic in any way, so... office joke? Seeing what they can get away with?
Got a laugh out of me anyway.
