Lighthearted - What things do you do to annoy your OH for your own amusement?
I like to incorrectly 'correct' pronunciations of words while we watch telly purely because it drives him mad. So for example on a cooking programme the chef said 'zest' to which I said to dh, 'it's pronounced j'est, it's a French word' and other such utter bollocks! Amuses me greatly 
I also say shop names completely wrong on purpose or put the emphasis in the wrong place like, MatAlan, Tescos's, sporting direct etc.
Please share your little wind up ways
