A Spoonerism is an error in speech (or sometimes a deliberate play on words) where corresponding morphemes, vowels, or consonants are switched. Some examples:

Punk in drublic (Drunk in Public)

Tarp as a shack, and not bolding hack (Sharp as a tack, and not holding back)

Pobody’s nerfect (Nobody’s Perfect)

It’s a good thing magicians aren’t prone to these:





Here are a couple other types of linguistic slip-ups that I’m sure you’ve heard (or said):

A Malapropism is the substitution of a similar sounding word for another. The resulting sentence is nonsensical and usually humourus.

Examples:

Worst case Ontario (Worst case scenario)

…prostate with grief (prostrate with grief)

I’m not a pessimist; I’m an optometrist. (optimist)

A Mondegreen is when a listener mishears words, and subsequently repeats them incorrectly. This often happens with music.

Examples:

Excuse me while I kiss this guy (Excuse me while I kiss the sky)

Sweet dreams are made of cheese (Sweet dreams are made of these)
