I take a mouthful of mouth wash, gulugulugulu, no stop,
while gulu-ing, I lay on the floor, face up, and lift my legs up 45%
and keep them straight.  I keep my legs there until the I can't stand
the mouth wash any longer.
 
this way, I worked out my ab, and kills germs in my mouth.
 
shuo wei yi jian xuang diao ah.
