Lisa Effect (n). The positive change in someone's feelings from being bummed-out to being happy, because of a visit from or to someone named "Lisa". Recurring plot point in Scrubs (Season 2 episode 10, Lisa the "gift shop girl"), Cheers (Coach's daughter, 1982, (Season 1, Episode 5)), and Frasier (Lisa Maxwell, season one, the first 'Daphne'). All three examples are NBC products, maybe a coincidence. And don't forget Lisa Kudrow from "Friends". She is a go-to person when people are upset. Also NBC.
I felt like crap when I got up this morning, but got the Lisa effect at lunchtime, now I'm good to go.
