Handkerchief or tissue?
Bleh! Tissue. That reminds me of a story that a one of my old work colleagues told me:
This guy was an avid mountain climber, and one day he was trecking through the Himalayas. There was a small group of them, and they were being led by some local guides. As they trudged through the snow, one of the guides leaned over and exhaled sharply over the snow, evacuating the contents of his nose. One of my boss's colleagues remarked:
"That's disgusting, spraying that mucus over the ground. Don't you have a handkerchief?!"
To which the guide replied:
"I think it's disgusting that you collect your mucus in a rag, and keep it in your pocket"
Here comes a dangerous one:
Pepsi or coke?
