  We compute the p-adic L-function (in the sense of Pollack-Stevens and
Bellaiche) of the "evil twin" Eisenstein series. We use Solomon's Shintani
cocycle to construct a p-adic Shintani modular symbol, and show how to
specialize this modular symbol to overconvergent modular symbols with the same
p-adic L-function as evil/critical-slope Eisenstein series. This gives a new
proof of recent results of Bellaiche and Dasgupta.
