Knock Someone's Socks Off
(enthuse and excite)Hi, John. What's new?
Oh, nothing too much with me, but you ought to see Alfredo's new car. It'll knock your socks off!
So, he finally got that Italian sports car he's been dreaming about.
He sure did! When you see all the custom features that it has, you'll get so enthused and excited you won't know what to do!
Boy, I can hardly wait to go for a ride in it!
