Laptop becomes key less

Yesterday we accidentally left our laptop on our mattress and thats one place easily accessible to our little brat...it was hardly five minutes after that...we noticed that he had skillfully plucked out the X,B,N,<,V keys from it.....And b was missing also.....my husband painfully spent an hour and somehow managed to put the keys back in place...Despite that some of them are standing at an angle of the Leaning Tower of Pisa right now...i searched all over the place for the missing B but could not find it all....Full of frustration i started typing a message on facebook when i realized that the space bar was not working...and viola!!! our missing B was under the space bar....we used my tweezer and managed to pull it out and put it back in place.....
