Does anyone recognise this?

This stuff started sprouting up all around my yard in the last week or so.  It is growing fairly fast as well.  Anyone know what this is?

This lawn was put in some time last year before I purchased this house.  I am pretty sure it was a roll-out sod installation. 

edit: this image makes it looks a lot taller than it is.  It is about 5 inches long, but they lay flat in the yard.

Alas, your photo shows a bad weed. Here is what my book says of it on page 248:

Corn Bindweed (Convolvulus arvensis). The name Convolvulus is derived from the Latin convolvere, meaning “to entwine,” and arvensis, meaning “of the fields.” It thrives in sunny, cultivated ground. This common weedy European perennial grows from rambling, starchy roots; the tops die in winter. It blooms mostly from May into July; flowers are ?–2 inches wide and shallowly funnel-like. Colors are white, pink, or mixed—set off prettily against deep blue-green foliage of arrowhead leaves. No soil is too dry or site too sunny and hot. It would make a swell drought-tolerant garden ornamental if it didn’t insist on conquering. Each stem trails along the ground or wraps itself around something, and the whole plant merrily twines along. Some call it: small, field, or lesser bindweed, devil’s guts, creeping Jenny, bearbind, ropebind, cornbind, possession vine, and smallflower morning-glory.

Good luck; you better start plucking and plucking.

Wonderful.  I just noticed it starting to climb up a few things near the house just yesterday too.  Perenial?  What a pain.

The flowers are kind of pretty aren't they?  I guess I'll start plucking it out this weekend. 

Plucking it out?! 
Why?  It's a totally beautiful plant improperly called a weed.  There is no scientific designation for the word weed.
It will bloom well into the fall and if you provide it a trellis or something to climb on it can add some real beauty to sometimes otherwise unattractive areas.  Honey Bees love it and it needs almost no care at all and grow in places where nothing else will grow.  It's related to morning glories which I plant all the time.
  My old house had this really ugly porch on the front of it and the morning glories and bindweed would grow up to cover it every year and during the warmer months you never knew how bad that part of the house looked.
  Don't pluck it out.  Groom it and train it to grow where you want it.  It will enhance your property all season long.

In the right place I am sure it is rather lovely.  But this is popping up in the middle of my front lawn.  Not really a great place for a climbing plant.
