  Title: Normal as the Next Guy
  Passage: Normal as the Next Guy is the 6th and final album released by The Knack in 2001.  It marks the 4th comeback attempt by the band after its second album, "...But the Little Girls Understand", failed to achieve the success of the band's début album.  Allmusic critic Mark Deming noted that the album finds songwriter and lead singer Doug Fieger having resolved his issues with women, but has not "found a subject that appears to compel him nearly as much as the treacheries of girls once did."  Therefore, Deming feels that compared to older songs by the band, the songs on "Normal as the Next Guy" "may be more pleasant, but they're not as interesting."  The "Rolling Stone Album Guide" gave the album a 3 star rating, as high as the group's début "Get The Knack", and higher than any other Knack studio album.

It reached No. 11 on the "Billboard" Hot 100 chart and No. 66 on the British charts.  It also reached No. 20 in New Zealand.  The song has since been covered by a number of artists, including The Chipmunks, Ben Folds, The Chubbies, and The McRackins.
