On the last day of production of How I Met Your Mother, Alyson Hannigan and co-creator and executive producer Carter Bays implored fans to get #PamFryman trending on Twitter.

"I am the one person who is not on Twitter. At one point, I got a text from one of my kids that said, 'Mom, you're trending,'" Pamela Fryman, the show's longtime director, tells TVGuide.com. "I was like, 'Is that good?' Carter, when he found out, started hashtagging me up. It was so funny. I was like, 'Guys, I'm trending!'"
