A sad entry in the book of life. The rap/pop band's one-hit wonder, which was quite tuneless in the first place, -'s chorus went "NOW HOO LET THE DAWGZ OWIZZOWT WOOF WOOF" and had thusly created the most annoying catch phrase of the early 2000's.
Jim: Hey, last night, a guy broke into my house and left the door open, thus creating a gateway for my Shnauzher to escape torture.

Bo: Oh, really? I bet he REALLLY let the dogs out. HA HA HA HA HA HA HA!!

Jim: Hey didn't the Baha Men sing that?
