  Motivated by recent anomalous CDF data on $Wjj$ events, we study a possible
explanation within the framework of the two-Higgs doublet model. We find that a
charged Higgs boson of mass $\sim$ 140 GeV with appropriate couplings can
account for the observed excess. In addition, we consider the flavor-changing
neutral current effects induced at loop level by the charged Higgs boson on the
$B$ meson system to further constrain the model. Our study shows that the
like-sign charge asymmetry $A_{s\ell}^b$ can be of ${\cal O}(10^{-3})$ in this
scenario.
