Coolant Puns

Recently, my mother started smelling a coolant leak from our refridgerator. She called the repair man and he started work. Several hours later, he had his diagnosis, and it wasn't good. The whole machine was going to need to be replaced. Just as he was finishing up, my dad walked in. My dad asked the repair man what the damages were, and he explained that the coolant intake had sprung a leak. The whole unit was sealed, and air was now getting in and contaminating the entire system. The repair costs of the fridge would be about the same as getting a new one. My dad just sighed and looked at his hands.

Dad: "It sucks." He looked at the repair man with a goofy grin on his face. The repair man thought for a moment before answering.

Repair man: "Yeah... it does suck." Then both men cracked up laughing.

I was texting my dad about using some left over coolant for my car since it's a specific type. This was our exchange.

Me: Cool if I come by after work?

Dad: That's coolant
