I should imagine Dave spent quite a bit of time as a Minister with writer's block - deliberating over which font to use.
Worrying recently whether the letters "D.H.L" should always be in a Courier font, I began to ponder the strange names that typefaces have been given over the years.
Arial - Always use this if you want to improve your reception.
Verdana - Invented by the bloke who was left in the office whilst his colleagues went to lunch. "Verdana Pub"
Sans Serif - A lawless French village
Rockwell - Useful for promoting the status quo.
Comic Sans - Used for the titles of "My Family"
