Now here's something I've never seen before. Blending two blends together to make...a blend? In this scene from the 1980 comedy Caddyshack Ty Webb (Chevy Chase) offers to make a drink for a group of belligerent men as a way of calming them down. Watch closely as he proceeds to pour some J&B and what appears to be Cutty Sark into the same glass. Great Movie. Funny scene.
The clip takes place at the 1:11 mark in the film. Check it out below, and click here for the previous J&B sighting.
