Inset:Andrew Burton/Getty Look who got to geek out with Sheldon and Amy? Retired Arizona Congresswoman Gabby Giffords and her husband Mark Kelly recently stopped by the set of The Big Bang Theory. The couple were there as fans, not guest stars, and they got to snap a shot with cast members Jim Parsons (Sheldon Cooper) and Mayim Bialik (Amy Farrah Fowler). “What an honor and privilege to meet @gabbygiffords on set with @therealjimparsons,” Bialik posted on Instagram. “What a woman she is. Wow.” It’s been four years since Giffords, 44, was shot outside a supermarket near Tucson. She recovered some ability to walk and speak but retired from her congressional seat in January of 2012. On March 15, she and her husband, who is a retired astronaut, appeared on CBS Sunday Morning and talked about how the “slow pace” of new gun control legislation. She said “maybe” when asked about running for office again, while Kelly may consider it “under the right circumstances.” The Big Bang Theory airs Thursdays 8 p.m. ET on CBS.
