Versions
"Irony" was pre-released on Melon on February 6, 2007. The original studio version featuring the original line-up (Min Sunye, Park Yeeun, Lee Sunmi, Kim Hyuna and Ahn Sohee) is available on The Wonder Begins and on their debut studio album The Wonder Years. The song was later re-recorded for the Japanese release of their greatest hits album Wonder Best and features the line-up consisting of Min Sunye, Park Yeeun, Ahn Sohee, Kim Yubin and Woo Hyerim, with the vocals of the former members removed.

Music video
A music video was produced for "Irony" to promote The Wonder Begins. The video begins by showing the group members casually hanging out at a house, when Sunye enters in a depressed state. Her groupmates sit around her and Sunye tells them about her cheating boyfriend. Sunmi locates him through their computer, Sohee activates a satellite dish for remote surveillance, and Hyuna uses a voodoo doll to embarrass him in front of his new girlfriend. The girls later enter a club where he is with his friends. Sunye blows him away, causing a gust of wind, and he falls down a wall. The video ends with the girls laughing at him and walking away.

Critical reception
The Wonder Begins received generally mixed reviews from music critics. Jeong Seong-ha, Han Dong-yoon, Yoon Jee-hoon of Korean web magazine IZM gave "Irony" unfavorable reviews, who felt that the song lacked innovation, comparing the song to works of older artists such as g.o.d and Rain. YesAsia wrote a positive review of the single album, describing "Irony" as a "catchy, up-tempo hip hop number" and "Bad Boy" as an "innovative electronic R&B song". They concluded that, "The Wonder Begins marks a very promising start for K-pop's newest sensation." In a retrospective review, Billboard wrote that "'Irony' is pretty dated with its R&B-pop styling and redundant beat, but the sleek, hook-filled chorus was filled with promise."
