urban commands results not working.

[Ant]

Does anyone know why my rbots won't know their !urban* commands
correctly? I tried the offiical one in irc.freenode.net's #rbot
channel and it was fine:

[07:11am] <Ant> !urbanday
07:11AM <Bender> Ant: nontroversy not found
[07:12am] <Ant> hmm
[07:14am] <Ant> !urbanday
07:14AM <Bender> Ant: nontroversy not found
[07:15am] <Ant> !urban MTV
07:15AM <Bender> Ant: MTV not found
[07:19am] <Ant> !urbanday
07:19AM <Bender> Ant: nontroversy not found
[07:19am] <Ant> !urban
07:19AM <Bender> Ant: bakayarou not found
[07:19am] <Ant> @urban
07:19AM <Flexo> Ant: Brazilian+Wax not found

I wonder if I have something missing. Thank you in advance. :)
