pertend to puke by gagging yourself. or spill orange juice on carpet with soft bread chunks so it looks like you puked also.

Take a fat turd in your pants 8)

i say that your not feeling good and put some hot water on your forehead and dry it and just tell her you will lay down all day

I've got the best way

GET A LIFE!

eat some bad food, like raw chicken, then you'll be feeling pretty bad by tomorrow

okay what you do is put a penny under your tongue and when you take your temperature it'll be in the hundreds since copper is a good conductor of heat it heats up and bammmmmmmmmmmmmmm fever and stay home

this is what im doing get like tomato soup or chicken soup and wake up extra early and say you threw up!!!!!! works every time

Don't say the usual "My stomach hurts"
Say "I have a headache"
Or tell her "Mom, you want to see me do a cool trick on my skateboard? Then "Fall" "

Sit in the bathroom for 10 minutes before you go to school. When she knocks on the door, tell her your stomach is really hurting you and then make a low fart noise with your hands(make it real)

Also bring something in the bathroom to keep you busy.!!

Hope I helped, works for me every time

get hit by a car.

pretty convincing...
