Little alien that looked like skeletons, had needles that came out of there fingers tips and when the stuck people animals etc. they became drunk except the town drunk. Can't remember the name of it.

Invasion of the Saucerman

...To everyone's amazement, the loveable Artie turns out to be alive but drunk. The kids deduce the aliens inject their prey with alcohol and if you're already drunk, like Joe was, then you die....
