While I don't get that upset about you,Yiz, Yous, Ye etc. there is one thing that I find quite irritating and that is where people use the Present Participle in situations where I would have thought the past participle was more appropriate.

For example many of the English people reading this post will probably think "That Declan needs his head examining", whereas I would think it more correct to say "That Declan needs his head examined".
