What kinda Gak did you have? From what I remember as a kid, Gak was REALLY over hyped. The stuff was more liquid than slimy, smelled liek feces covered in rubber, and left this awful residue that would take liek an hour to scrub out of your hands. Also, if it touched the carpet, that spot of the carpet needed to be cut out and destroyed because you could never clean it. So all in all, good product!
