For one single second, at least, Olive Garden was the most popular pasta joint in the country.

The company put 22,000 of its once-a-year Pasta Passes on sale on Thursday at 2 p.m. — and they sold out in less than a second, the Darden Restaurants-owned chain said.

The $100 passes entitle the holder to eights weeks of unlimited food beginning Sept. 25 — including pasta, soup, salad and the famous breadsticks.

It is the fourth year of the Pasta Pass. The eight-week period is one week longer than last year’s Pasta Pass span — which also sold out in less than a second.

Last year, 21,000 passes were sold.

The promotion, in its fourth year, sold out in a split second last year as well and was expanded this year by 1,000 more passes.

Some that were lucky enough to hit “buy” at the right time seem more interested in profits than pasta. There were no fewer than 41 Pasta Passes listed on eBay early Thursday evening.

One had nine bids, the highest for $150.01.
