31 May 1669 was the last diary entry recorded by Samuel Pepys. On this day in 1859, the clock at Westminster began keeping time* and 2200 people were killed in the Johnstown Flood in 1889. Celebrating birthdays: Clint Eastwood, John Prescott (who only wants a toilet seat for his birthday this year), Peter Yarrow, Terry Waite, Sharon Gless, Brooke Shields and Colin Farrell. It is the Feast of the Pentecost for Christians.
*I'm now thoroughly confused. I always thought "Big Ben" referred to the bell. Wikipedia says it's the clock & tower. I'm sure someone will set me straight.
