You could go as a marmot, it is groundhog season, after all
I would go with ashes on my face and carry a maxwell house can.
I really need to see this movie.
Go as a German nihilist
This is all a whoosh, right?
Somebody please, please tell me The Big Lebowski has not achieved cult-film status!
Don’t get out from under that rock much, do you? 
Yes, yes, my little cephalophage, we’re all whooshing you. How could you doubt?
You have no frame of reference, glutton, you’re like a little child who wanders into a thread, you’re out of your element.
Darn and drat, that’s what I was going to say. The first time I watched the movie I had to pause it to almost literally laugh my ass off at the marmot scene.
Damn, I’m getting old. I’ve seen this movie dozens of times, and the marmot scene is only tickling the edge of my brain pan. Could somebody please refresh my memory?
The bad guys break into the Dude’s house and put a marmot in the bathtub with him to get his attention.
It works.
There is a subtle running gag in the Big Lebowski that gets funnier when you rewatch it: the fact that the Dude keeps paraphrasing lines other characters have already said. If I were at a Lebowski fest I would totally paraphrase the other guests, only for my own amusements.
Nitpick: the “marmot” in the movie was actually a ferret. Fortunately for the fest in question, Illinois does not require a permit to posses a ferret. (Marmots I’m not so sure about)
So you’re saying you’d reword what you heard from others just for a laugh?
Yeah. Of course, I would have to make it seem natural and not all random like. All in the style of the Dude.
e Oh, I got it. Whoosh.
