From March 15 through May 31, Ben & Jerry's scoop shops are serving up the Liz Lemon Schmake, which consists of the new Greek Frozen Yogurt flavor, Liz Lemon, blended with Berry Berry and sorbet.

In addition to the Schmake, Ben & Jerry's is offering the Liz Lemon Waffle Bowl Sundae.

The item includes a freshly baked waffle bowl, Liz Lemon Greek Frozen Yogurt, Berry Berry sauce, and whipped cream.

Liz Lemon is a Greek frozen yogurt with blueberry-lavendar swirl. The flavor helps raise awareness for Jumpstart, a national early education organization that actress Tina Fey—whose character on "30 Rock" inspired the Liz Lemon flavor—has supported.
