Abstract
--------
We present a search for anomalous kinematics of ttbar dilepton events 
in ppbar collisions at sqrt{s}=1.96 TeV using 193 pb^{-1} of data 
collected with the CDF II detector. We developed a new a priori 
technique designed to isolate the subset in a data sample revealing 
the largest deviation from Standard Model expectations and to quantify 
the significance of this departure. In the four-variable space 
considered, no particular subset shows a significant discrepancy and 
we find that the probability to obtain a data sample less consistent 
with the Standard Model than what is observed is 1.0 - 4.5 %.
