McDonald's Shamrock Shakes Are Back Again

Hey, heads up, Shamrock Shake fans! They're back at the local McDonald's for a limited time, and for the first time they're being offered nationwide.
I loved Shamrock Shakes when I was a kid, and they're still my faves. Ever since I had my first one when I was eleven, I've looked forward to the St. Patrick's Day season when Mickey Dee's would bring them back.
i don't like the new default way McD's serves their shakes as part of the McCafe lineup, though - really, who needs whipped cream and a cherry on top of a shake?  I got one all decked out in the finery one time, and was totally unimpressed.  Just plain for me from now on, please.
