The exclamation points are overkill. You've got a great line, no need to be insecure about it. Grade: B.

A local plastic surgeon.

A tad long, but very memorable. Grade: A-.

I've seen many "drop your pants" dry cleaner slogans, but this one wins because of the "prompt attention" ending.

EDIT: "Drop your pants here and receive prompt attention." Always look to make any tagline shorter. ALWAYS.

Grade: B-.

Not original, and unappetizing. Grade: D.

Local cement company.

So? So can every other cement company.

Grade: D.

But what do I get out out doing business with you?

Grade: C.

Brilliant.

Grade: A+.

Hey, Harvard, right?

Grade: B.

Rhyming can be good.

At least their slogan tells you what they do.

Grade: B-.

Of Superior, Wisconsin.

Usually, I take off points for vulgarity.

But here, it works perfectly.

Grade: A.

Of San Francisco.

WHAT?!?

Grade: F.

And, the best local tagline in history.

It's so good, that, after using the line for nine fucking years, Northampton's Sofa King was reprimanded by the UK's ASA, because, "[the ad] could be interpreted as a derivative of the swear word 'fuck', which consumer research had found to be a word so likely to offend that it should not be used in ads at all, even when it was relevant to the name of a product..."

BULLSHIT.

Grade: A++.
