A Lame joke~

The joke start~~

When you visited to a house..
..you knock the door.
The sound is " Knock, knock..."

When you visited to somebody blog..
..you read him/her blog.
The sound is " Blog, blog..."

The joke end~~



I suddenly think about this joke...
...i know is quite lame, but dunno.
Just wanna write it out...
