Three of my faves:
1) "Just between you and I."
"They gave it to my wife and I."
(Worse) "They gave it to he and I."
It's me. Me. Me. Me.
And him. Not he.
2) "These type of things."
I hear this from sportscasters all the time. It's types. These types. Of things.
3) Listen for this one. You will hear it more often than not.
"The fact of the matter is, is ..."
"The problem is, is ..."
The subject has become not just "The fact of the matter", but "The fact of the matter is." The "is" gets said twice. Listen. You will hear it often.
This isn't grammatical esoterica. It's pretty basic.
So don't call me a snob.
