William Archibald Spooner (1844-1930), British cleric and scholar.
Spooner is famous for spoonerisms, which are accidentally humorous transpositions of sounds. For instance, StackSmashing and SmackStashing, or Would you like a hazel nut? and Would you like a nasal hut?.

Does that page contain him scolding a student?
The only Spoonerism recorded (as opposed to merely attributed) occurred in 1879 at the New College Chapel when announcing the next hymn as: "Kinquering Congs their titles take." Quoted in The New Penguin Dictionary of Quotations by J M Cohen (1992) page 403.
There is a story that he also spoonerized actions: when someone accidentally spilled some salt at table, the story goes that he carefully poured a little red wine on it, to give that characteristic little pile of pink salt that adds colour to so many dinner parties :-)
I don't get it.
