Before Johnny Galecki ever stepped foot on the Big Bang Theory set, he had genuinely walked away from acting entirely, pursuing a completely different career path in the Midwest.
"My career has not been seamless," Galecki told Entertainment Tonight. "Immediately before 'Big Bang,' I was in Wisconsin studying plumbing." After a lull of nearly a year without landing acting work to the point where he began selling his own belongings, including his cello a friend named Bill in Chicago offered him an unexpected suggestion: "You would be really good at bathroom and spa design."
Galecki committed fully to the idea. "I said, 'If I go and I learn I'm going to go to Wisconsin where the Kohler plant is and then learn the plumbing of it all' and I did." With his friend agreeing to help fund the venture, Galecki relocated to Wisconsin to study plumbing at the Kohler facility, genuinely preparing to open his own design studio.
Then, while still at the plant, opportunity intervened. He received a call to guest star on a project, which led to his Broadway debut and it was during that same stretch that Chuck Lorre reached out about The Big Bang Theory.
Galecki has reflected on the moment with genuine wonder, once saying, "There's part of me that feels like there's definitely a nearby parallel universe and I'm still studying plumbing in Wisconsin."
