Scream and shout...

once in a while...i will feel like doing the above...

i remember that when i was younger...prob in my sec sch days...i would cover my mouth with my pillow and juz shout...and shout...and when that doesnt work...i will pop my head out of the window and juz let go for a couple of seconds....and quickly retract my head to avoid being spotted...much like how the cowardly tortoise would react when alarmed...

otherwise...a more subtle and less effective alternative would be to put on my earphones and let the music flow...while humming or singing along...softly...till my eyelids become droopy...

the best method would be to get into the car late at night with no particular destination in mind....wind down the windows...get to the expressway and slam down the right foot...while letting out an occasional scream/shout...

at the end of it all...meet up with a buddy for a drink and smoke...

results guaranteed.
