GOOD ONES: Really big hangover? A DAZE LIKE NO OTHER

Degree in math NTH
Commercial developers AD MEN [
Mad Men should be coming back in a couple of months]

Better part of a loaf? HALF [How can a half be
better? Because "half a loaf is better than none."]
BTW: I CALL EM AS I SEIZE EM is a clever theme entry but only English teachers use AS conjunctively --- everyone else uses LIKE. (The rest of the expression is "An if I don't see em, I make em up.")
