MacGyver: A man once said he went to a fight and a hockey game broke out.
Jimmy: Take my advice, stay young.
MacGyver: I'll try.
MacGyver: (Climbing up an elevator shaft) I've never minded checking out bars or car lots. That's because they're usually not ten stories up.
Jimmy: I lived by the beach when I was a kid in Jersey City. Well, it really wasn't a beach, it was a drainage ditch. But my mother said it was a beach and I believed.
Jimmy: Well, like I used to tell Mikey, dreams are important, otherwise sleep is just eight hours of nothing.
MacGyver: I like alfalfa sprouts for two reasons: lots of minerals and they don't stain your clothes.
MacGyver: If Simmons picked this neighborhood because of its low profile, he made a great choice. Everything you always wanted in a slum, and less.
MacGyver: You know, I bought your whole story. Boston Braves.
MacGyver: Bad knees.
MacGyver: Being a friend.
Jimmy: Our Ralph is so dumb, he'd study for a blood test.
Jimmy: I owe you one, MacGyver.
MacGyver: How can you owe a friend?
Ballplayer: Hey, Louie, I need some oil for my glove.
Jimmy: You don't need oil, you need glue. Two errors on one play yesterday.
Ballplayer: I lost it in the sun!
Jimmy: It was a ground ball!
Pete: Mmm, this is great. Did you make this?
MacGyver: You're supposed to heat it.
Pete: Mmm, I like it cold.
MacGyver: I didn't think you'd go in for whipped bean curd.
(Pete looks in disgust)
MacGyver: Electrical locks are designed to open when a person inside hits a button. Nice thing about these kinds of locks is that if you give 'em a power surge, they don't know which side of the door you're on.
MacGyver: The penalty box is hockey's version of solitary confinement. Except you serve your time in front of a rink full of people.
MacGyver: When I was a kid, I was known as a rink rat. The first one on the ice and the last one off it. So as a bonus for my last assignment, I asked Pete Thornton to arrange a scrimmage with the Squires. I was kind of nervous lacing up my skates, but once I was out there it was just like old times.
MacGyver: Put twelve guys carrying sticks in an enclosed area and sooner or later… men will be boys.
