That's Mencia I think...
I believe that was the episode that they found a ship with a bunch of nakid officers frozen on another starship that had blown the hatch.
It was some sort of polywater that well...acted like shrooms...
I believe that was the episode where Natasha Yar got it on with Data.
Yar was at least slightly attracted to Data and had sex with him while under the influence of polywater intoxication. She later told him that the incident "never happened". (TNG: "The Naked Now") Data still felt a special connection to Tasha. He kept a holographic image of Tasha to remember her. When Data's rights as a sentient being were called into question, his romantic encounter with Tasha was a strong influence for Judge Phillipa Louvois to rule that Data was in fact a sentient lifeform.
I gotta get me some of that polywater...
DAMMIT I'M TURNING INTO BOB!
