Ruby wedding
From Tardis Wiki, the free Doctor Who reference
Brian and Hazel were congratulated on their ruby wedding by the First Doctor as part of a long series of personal interactions from the Doctor that started when he began expressing good tidings to viewers at Christmas. Steven Taylor heavily disliked this and thought it should have been nipped in the bud then. (NOTVALID: Doctor Who? 144)
Behind the scenes
A ruby wedding is a couple's 40th wedding anniversary.
