DOCTOR: She has over 70% burns to her body, what happened?

<FLASHBACK TO SUPERMAN UNDRESSING WOMAN WITH HIS EYES>

SUPERMAN: ....she spilt coffee.

A nice visual, just not very strong on its own.

I think the joke is funny, but I don't know how you'd show that he was undressing her with his eyes, not deliberately lasering her.

Good joke setting doesn't sell it though

I think if its Superman and Batman discussing a failed date and Bat says what went wrong

and Supes I forgot about the laser vision and undressed her with my eyes

Some good points, thanks guys.
