Clogged Sink

Dammit! I have a clogged kitchen sink!!
I really dont know what could have happened.
Yesterday was the last day I remember using the
sink. The only things I remembered putting down
in the garbage disposal was

1) some rice
2) some corn
3) some left-over "sabow" from my Chicken Adobo

Crap ... and my landlord/maintenance cant help because
in my lease we (tenants) are responsible for our garbage
disposal!! We are NOT suppose to put into the garbage
disposal

1) rice
2) pasta
3) lard / grease

Im guilty yes ... but I've put rice in the garbage disposal before
and was never clogged!
