H, E, double N - I ...

Hennigans - one of those Seinfeld-world only references that pops up in a few episodes. When there was whiskey - there was Hennigans. A few appearances below - any others?

"The Red Dot" (1991):
Kramer: Okay, well what am I drinking? What do you got?
Jerry: I got a bottle of scotch my uncle gave me. It's Hennigans. It's been here for two years. I've been using it as a paint thinner.
Kramer: That is *damn* good scotch. I could do a commercial for this stuff. Mmmmm, boy that Hennigans goes down smooth. And afterwords you don't even smell. That's right folks. I just had three shots of Hennigans and I don't smell. Imagine, you can walk around drunk all day. That's Hennigans, the no-smell, no-tell scotch.
Kramer: Say you got a big job interview, and you're a little nervous. Well throw back a couple shots of Hennigans and you'll be as loose as a goose and ready to roll in no time. And because it's odorless, why, it will be our little secret. (singing) h-e-double N, I...

"The Parking Spot" (1992)
Elaine: Oh god, I need a drink, do you got any Hennigans here?
Jerry: Yeah, under the counter. What happened?

"The Boyfriend 1" (1992)
Elaine: Wait a second wait a minute, You jealous of him or you jealous of me...?
Jerry: Any Hennigans around here?
