Though according to Wiki - Spoonerism most attributed to the Rev Archibald Spooner are probably apocryphal.

What I have read says that he was an albino and that spoonerisms are not uncommon with that condition.
And the switcheroo was more general like when he was introduced to a person and said "was it you or your brother who was killed in the war?"
