A rooster, a crocodile and an elephant are walking through the Mayfair shops. "I think I'll buy a feather boa" says the rooster. "I think I'll buy a leather wallet" says the croc. "How 'bout you, elephant?" they ask their shopping companion. "I'm going to buy a telephone" he replies. "A telephone?! Whatever for?" comes their reaction. The elephant raises his large head and announces "Trunk calls".
