Entertainment Time: Pity to all the male students

when i was walking up to my hostel room, suddenly i saw some thing stick outside one of the unit's wall, the paper that stick on the wall is as below:
Do you understand what the warden trying to say??? izit he forcing the students inF3D to do 'Kerja Paip' (paip as in paip or biological paip???) or he wanted to inform the studen for the moment, they are not allow to enter because there is some maintainance work in going on??? I tot my english already bad, who knows the guard lagi teruk then me, even bahasa kebangsaan also 'Tak dapat kredit agaknya'...haha...hope you all enjoy it...
