A blonde was shopping at Asda's and came across a shiny silver thermos. She was quite fascinated by it, so she picked it up and took it to the till to ask what it was. The operator said, 'Why, that's a thermos... it keeps hot things hot, and cold things cold.' 'Wow, said the blonde, 'that's amazing.... I'm going to buy it!' So she bought the thermos and took it to work the next day. Her boss saw it on her desk. 'What's that,' he asked? 'Why, that's a thermos... it keeps hot things hot and cold things cold,' she replied. Her boss inquired, 'What do you have in it?' The blond replied...'Two ice lollies and some coffee.'
