For $100, a Groupon (GRPN) employee will come to your house and tuck you in at night.

That's an actual offer from the daily-deals company -- and two Chicago residents have bought in. The employee, Ben Kobold, promises to pour you a glass of water and make sure you're comfy before leaving.

"Ben's sinewy, well-groomed fingers delicately raise each sheet and blanket over your body until you're comfortably bundled," the offer reads. "Careful not to disturb any children who may be in the adjacent room, Ben leans in and uses his summer-breeze-like voice to gently sing you one of the five lullabies he has authored."

Groupon may have lost any hope of a decent share price, but it clearly hasn't lost its sense of humor.

A company spokeswoman played it straight when contacted by Reuters. Julie Mossler said the deal was legitimate. "There's a real demand for a service like this," she told Reuters. "There's nothing strange about it. It's very straightforward." Groupon is making the offer only to people sleeping within five miles of the 60601 ZIP code.

The offer shows a photo of Kobold wearing gloves to tuck someone in. Mossler said the company prefers that he wear gloves during the service. And the offer states that Kobold will be bringing companions along, presumably for his safety.

The deal, which ends Wednesday, is typical of the irreverent humor in Groupon's culture. The CEO drinks beer during the company's town hall meetings with employees. Groupon's daily offers often contain a zinger or two, like this one noticed by Success magazine:

"Shopping for gold clubs is a lot like buying a used car: always get the one that drives into the fewest trees." The joke was for an offer for golf club regripping services.

Groupon can be allowed a little levity this week. Its share price has been climbing after dropping below $9 on Monday. The stock was upgraded to "hold" by an analyst at Stifel Nicolaus, who said that "growth areas could develop."

But Groupon is still a long way from the $20 it priced at last November in its disappointing IPO.
