Good: French Fries With Mayonnaise. I got tuna fish sandwich for lunch today. The sandwich came with a small tub of mayo. Rather than use the mayo on the sandwich as intended, I used it as dip for my french fries. It was actually quite good (and is apparently popular overseas).
Bad: Driving With Vuvuzelas. As a result of their incessant use at the World Cup, people have been hating on vuvuzelas. This hatred gets taken to a whole new level, however, when you're driving down a narrow street and the people in the car behind you won't stop playing their vuvuzela. (Unfortunately, this is a true story; it happened to me yesterday.)
