The Jerk----one of the greatest movie comedies EVER!
---don't remember the thing about the oil cans, though,
my favorite line in the movie is when the tough motorcycle daredevil "Patty Bernstein" tells Navin she will try to guess his weight, so she clutches his butt with both hands, and feels around, and at length, he laughs and says "WOW! You're really trying to be accurate!"
OH YES!!! That was M. Emmett Walsh as the gunman, looking down on the station from his car, which was parked halfway up a hill, I think. Prior to finding him, I remember him looking through the newly issued phone book,(the same new phone book Navin got so excited about, finding his own name in it, and thinking that made him famous) opening a page at random, sticking his finger down on the name "Navin Johnson.... sounds like the typical loser!!!! BTW, the owner of the gas station, I'm sure you remember, was Jackie Mason. That movie is a favorite of my wife's and mine, and we having been using and quoting lines from it on a monthly basis for the last twentyfive years.
