Regarde(z)-moi ça !
"Regarder" is one of the most commonly used verbs with this idiosyncratic construction, there being more to the function of "moi" than meets the eye.
I wonder what other verbs can be used? I don't suppose practically anything will do, will it? What do you think about:
Visez-moi ça.
Mangez-moi ça.
Incidentally, I'm not talking about examples like the following where the use of "moi" is required and makes perfect sense.
Expliquez-moi ça.
