In Australia coming out of a NRL game one day, someone shouted to his mate "Alan"........and me and two other people in the crowd who didnt know each other started shouting "Alan, Alan, Alan" in the voice.
Everyone around was giggling..........and then one shouted "Steve"....and the place cracked up.
Just shows how niche and funny this was to that generation.
Never gets old.
I still tell the Lion & Giraffe joke now...lol
