Do they make pens for that?

For the past few weeks, construction-type guys have been renovating the parking lot outside the place where I work.  We're getting new planters, new sidewalks, new lightpoles, new brick walkways, and new asphalt for the actual parking lot.
I've had numerous opportunities to imprint all sorts of things in wet cement, and have chickened out every time.

Top 10 things I could have written in the wet cement:

1.  "If only you'd been here an hour earlier."

2.  "Never trust anyone who doesn't love bacon."

3.  "Kiss me before you walk all over me."

4.  "In case of extreme stress, hit head here."

5.  "In another universe, you would taste like chicken."

6.  "Can I borrow 20 bucks?"

7.  "Anxiety smells like fake nachos.  No, wait; I'm thinking of Doritos."

8.  "What's that under your toenails?"

9.  "Please present this coupon for one free hug."
