Grumpy Old Men

Grumpy Old Men is a 1993 comedy starring Jack Lemmon and Walter Matthau. It features two, well, grumpy old men, John Gustafson (Lemmon) and Max Goldman (Matthau) who've been neighbors for over 50 years and bickering for most of it, all the while ice fishing on the local lake and putting up with their kids (John's daughter Melanie, played by Darryl Hannah, and Max's son Jacob, played by Kevin Pollak) and John's nonagenarian father (Burgess Meredith). Then the pair's lives are turned upside down by a new neighbor named Ariel (Ann-Margaret), and their old feud goes all out to try and win her hand.

The movie's success spawned a sequel, Grumpier Old Men, which gave Max a love interest in Maria (Sophia Loren), and revived the old Lemmon-Matthau tandem for one more run in the '90s, including movies such as The Grass Harp, Out To Sea, and The Odd Couple II, thirty years after their original movie together.

Not to be confused with the British talk show of the same name.

This film and its sequel provide examples of:
"Max (in a bathtub): If I had know there was gonna be a nude scene in this picture, I would've asked for another million."
 * Badass Grandpa: Grandpa Gustafson definitely counts.
 * Cut a Slice Take The Rest: Variant - John brings beer to his dad at his ice shanty. Grandpa takes one out of the six-pack and hands it to John, then takes the rest inside and shuts the door.
 * Dirty Old Man: Grandpa Gustafson had more Unusual Euphemisms for sex than your average Fark thread.
 * Grumpy Old Man: Many of them, naturally. Max and John are the main ones, but there's also Chuck and John's father.
 * Hilarious Outtakes: The first film has an epic blooper reel before the credits, including a great stinger:

"Max: Hey, Snyder, why don't you do the world a favor? Pull your lip over your head and swallow!
 * Intimidating Revenue Service: The first movie's subplot involves the IRS repossessing John's house to pay back taxes.
 * Minnesota Nice: Averted, with the titular due spending all of their time insulting each other and pulling cruel pranks at one another's expense. Or maybe just played with, as by the end they're shown to be Vitrolic Best Buds.
 * The Reveal: Both movies have one:
 * In the first,
 * In the second,
 * Villainy Free Villain: Snyder of the IRS is just doing his job, trying to collect back taxes John owes. And (off-screen) he is actually fairly reasonable - Jacob talks him into waiving the late fees if the original amount owed is paid. Doesn't stop Max from insulting him and playing a few hilarious practical jokes on him.

Snyder: Ha ha! (under his breath) Asshole."
