Last year I had the boys convinced that we were shipping them off to military school for April Fools' Day. Son #1 actually cried. So this year the hub and I took son #2's bed and moved it into the other boys' room. Then I put all the dog crates and dog toys into Son #2's room and papered the floor in newspaper. I told them that they all have to share a room because Mom is getting ten foster pugs from MidAtlantic Pug Rescue. This was all Easter's idea, with help from Stripey the Sock monklet.
Update: Damn kids. The military college stunt ruined them for life. All three of them pretended to be thrilled with the ten extra puglets. Blast.
