Who knew there was so much history to them?

For example, the Candy Desk

Traditions associated with the Senate desks continue to evolve. A recent example is the so-called “Candy Desk.” In 1965 Senator George Murphy of California originated the practice of keeping a supply of candy in his desk for the enjoyment of fellow senators. In every Congress since that time a candy desk has been located in the back row of the Republican side, on the aisle and adjacent to the Chamber’s most heavily used entrance.

Or that senators carve their names in them?
