If you're ever in Nairobi, Kenya, you'll see a fleet of private buses and old vans called the matatu ("tatu" is "three" in Swahili, the original fare in shillings).

Each bus or van is "branded" with its own paint scheme and individual names, inspired (mostly) by Western culture. This one above is the "Princess Diana" with the motto "Thay [sic] Shall Bow ..."
