二、馬向陽的手機鈴聲Who let the dogs out歌詞：
Who let the dogs out
Who let the dogs out
Who let the dogs out
Who let the dogs out
When the party was nice, the party was jumpin
And everybody havin a ball
I tell the fellas start the name callin
And the girls report to the call
The poor dog show down
Who let the dogs out
Who let the dogs out
Who let the dogs out
Who let the dogs out
I see ya little speed boat head up our coast
She really want to skip town
Get back off me, beast off me
Get back you flea infested monger
Now I tell meh self dem man go get angry
To any girls calling them canine
Tell the dummy Hey Man, It's part of the Party!
You fetch a women in front and her mans behind
Her bone runs out now
Who let the dogs out
Who let the dogs out
Who let the dogs out
