Today marks the tax return filing deadline, so in honor of this occasion, here’s a look at the most dedicated accountant ever to grace the silver screen.

Louis Tully (Rick Moranis) is the nerdy accountant in Ghostbusters who’s in love with his neighbor Dana Barret (Sigourney Weaver). The bespectacled Louis is notorious for locking himself out of his apartment after lingering in the hallway to catch a few words with Dana, who barely gives him the time of day. But while Louis might not be lucky in love — or with locks — he’s a wiz at tax write offs.

And Louis knows how to pinch a penny. Instead of buying name-brand aspirin, he gets twice as many generic acetacylasilic acid pills for 35% less from Walgreens. Now that’s some savings!

For his four-year anniversary as an accountant, Louis celebrates by throwing a party complete with Nova Scotia lox and Brie cheese kept at room temperature and as well as breakdancing, Twister, and Parcheesi. Being the clever tax man that he is, Louis invites not friends, but clients to the gathering so that he can write off the event as a promotional expense.

Unfortunately, his clever tax deduction gets crashed by Vinz Clorthos the Keymaster, a minion of the shapeshifting god Gozer, who while in Terror Dog form possesses the unsuspecting Louis. On the bright side, the possessed Louis finally gets some real action from Dana, who’s equally possessed by another Gozer minon Zuul, the Gatekeeper. On the not-so-bright side, when it’s over, Louis can’t remember any of it.

But Louis doesn’t let it get to him. When the Ghostbusters finally free him from possession, Louis doesn’t bother asking them to explain what’s happened to him. Instead, he asks them, “Who does your taxes?”

Now that’s professional dedication!

So in honor of Tax Day, we salute you Louis Tully!
