This joke is obliquely related to coffee.... A blonde was shopping and came across a shiny silver thermos. She was quite fascinated by it, so she picked it up and took it to the clerk to ask what it was. The clerk 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 blonde replied........"Two Popsicles and some coffee."
