The second episode of America's Got Talent 2013 will feature even more eccentric acts than the premiere, according to NBC's latest preview.

It looks as though there will be a sword swallower, child ballroom dancers, dogs doing tricks, a gymnastics act, a black male opera singer and fire dancers. The promo shows small clips of each act intercut with the four judges looking on in awe.

The biggest tease of the promo, however, is a special act filmed outside the theater of a man balancing on a sky-high pole.

"This is the most outrageous audition I have ever seen," Howard Stern said of the act.

Judge Mel B made an appearance on The Tonight Show with Jay Leno Monday night to promote America's Got Talent. She admitted that it's difficult telling kids that they're not good enough, but "everyone else I love it, I love saying 'you're crap.'" She said that fellow judge Heidi Klum is good at rejecting acts as well.

As for last week's acts, many clips were uploaded to YouTube and it has been revealed which ones were more popular with the public. Getting over 640,000 hits, levitation act Special Head was far and away the most viewed clip of the premiere.

At 200,000 hits, Tone the Chiefrocca's performance of his "one-hit-wonder" Booty song was the second most viewed act while Anna Christine, the soulful 10-year-old singer who sang her rendition of House of the Rising Sun came in at 190,000 views.

Stats like this may be good indicators of which acts America will be interested in voting for in the coming rounds.

America's Got Talent will air its two-hour second episode of the season Tuesday night at 9 p.m. on NBC.
