up with which I will not put

Is anyone old enough to remember that line, supposed to be a witty riposte to the grammar pedant who stated that you should never end a sentence with a preposition?  That's  how I remember what a preposition is:

"a word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause, as in “the man on the platform,” “she arrived after dinner,” “what did you do it for?”"  

And yes, the online Dictionary confirmed my memory and yes, it was Winston Churchil, as I had suspected, who objected to the rule (originally derived from Latin grammar), by saying, "This is the sort of English up with which I will not put."

I've already complained about what I perceive to be incorrect prepositions, like bored of, instead of with. Here are a few more. Tell me what you think:

"oblivious of", not to

"immune to", not from  

"wean off", not from

and "wean on" not to

"annoyed with" a person

"annoyed at" being stung/bitten by a mosquito?  

Do mosquitoes sting or bite?
