DailyEdge.ie rounds up the TV shows that you’ll be tweeting about tonight and talking about tomorrow.

Tattoo Fixers (Channel 4, 10.35pm) If there’s one thing people love, it’s ill-advised tattoos. So it’s unsurprising perhaps that Channel 4 has devoted an entire show to people with tattoos that they deeply, deeply regret. Highly entertaining.

University Challenge (BBC Two, 8pm) It’s the second quarter final, Paxman has his fiercest question face ready, and eight posh people from England are about to be put through the wringer. Get ready to feel incredible because you managed to answer one question.

The Undateables: Holiday Romance (Channel 4, 9pm) The fifth season of Channel 4′s rather touching series about people with disabilities navigating the dating game continues. Tonight, two couples and one single set out on holiday in the hope of romantic adventures.

Everyone’s talking about: Tina Fey on Saturday Night Live

After Sarah Palin’s internet-baiting endorsement of Donald Trump last week, it was perhaps inevitable that Tina Fey would reawaken her legendary impression. She killed it. (Also, shut up, guy playing Donald Trump, you’re not funny.)

Or flick over for…

• Celebrity Big Brother (TV3, 9pm) The sh**show continues.
• Drunk Stoned Brilliant Dead: The Story of the National Lampoon (Sky Atlantic, 9pm) The story of the legendary US comedy outfit – with interviews from some of its most famous alumni. 
• Putin’s Secret Riches (BBC One, 8.30pm) BBC Panorama documentary on Putin’s wealth.
• The Dark Knight (ITV2, 9pm) Christian Bale doing his thing.
