The audience at home mostly has the final say on whether or not an act progresses to the next round on 'America's Got Talent,' but a strike ("X") from the judges is still pretty much the kiss of death for a competitor.

None of the six performers/acts from Tuesday night that received a dreaded red buzz from judges Piers Morgan (who gave five) and Howie Mandel (who gave one) are advancing to the semi-finals.

The lucky ones that did advance include dancer Beth Ann Robinson, bicyclist Matt Willheim, circus performers Gymkana and singer Kevin Colis.

Morgan pretty much sealed the fate of agile tumbler Breena Bell when he gave her a strike on Tuesday's show.

Why'd he do it?

Perhaps as a reminder that winning isn't everything on these reality shows, Pia Toscano was the guest performer on the penultimate results episode of 'So You Think You Can Dance' (Thu., 8PM ET on FOX). She only came in ninth last season on 'American Idol,' but that hasn't slowed her down in her career.

She performed her new single 'This Time' and proved that your finishing place in a reality competition is not necessarily a reflection of your talent. You don't have to win to be vindicated that you're great, or to be successful.

But Nigel Lythgoe was quick to remind everyone that the real winner in all of this is dance. Caitlynn made a strong case for herself against the one-two leaders in the judges' eyes, Sasha and Melanie, but was it enough to earn her a spot in the finale?

It was awfully nice of Lady Gaga to share the spotlight, even if it wasn't intentional with former 'So You Think You Can Dance' (Thu., 8PM ET on FOX) contestant Mark Kanemura. Kanemura has been very busy since his Top 6 finish in Season 4, but he can currently be found dancing on Gaga's 'Monster Ball' tour.

Gaga wasn't on the judging panel tonight, so she could perform a medley of 'The Edge of Glory' and 'You and I.'

While she sounded a little nasal at first (reminiscent of her first critiques on Wednesday's show when her sunglasses were pinching her nose), the sound improved as she went along and it wound up being a very entertaining performance.
