“All Over the Phone”

Last week I was watching a television show in which a character met up with another one to discuss something. When the first character found out what the second one wanted to tell him, he said:

That’s it? You could have said this all over the phone.

Really? He could have said it all over the phone? How about all over the floor? All over the counter? All over his body? What he should have said is:

That’s it? You could have said all (of) this over the phone.

Apparently even professional writers have trouble with the English language. 🙄
