Anybody remember a weird beer ad from the mid 90's

[PennyM3]

It started with a flies-eye-view of a garish dark green resteraunt and the fly drops into an old womans soup and she point it out to the waiter, he exclaims 'Flies? I love flies' and his tongue whips out like a frogs and eats it and then he turns into a frog. It had something to do with beer I think. It also has the Ride of the Valkaries playing when it was they flies-eye-view. Does anybody know what the advert was for or where it is available? It was brilliant! I remember it from when the film Beetlejuice first aired so it must have been 1994 or 1995.
