There was a time when the snooping strategy du jour was rifling through a friend's medicine cabinet.

But as times change, so do tactics and as you can see in an exclusive sneak peek clip from Thursday's Rules of Engagement, the hot way to currently spy on your friends is by checking their bank statements!

Rules of Engagement airs Thursdays at 8:30 p.m. on CBS.
