Fill your victim's coffee with instant coffee granules instead of grounds.
Prepare a few extra sugar packets with chloroform and hide one in the victims coffee cup. When they take a sip, the sugar will have a strange taste. 
Prepare some fresh-tasting creamer with cottage cheese mixed in -- watch your victim cringe as they realize they've been duped!
