David Letterman may start to get the impression people don't like him too much after a vandal broke windows and trashed the front of the Ed Sullivan Theater.

Last week a drunk busted through the front doors and trashed the lobby.  This week the damage wasn't nearly as bad.

Unlike the first random incident, this one was caused by a disgruntled man upset with Dave for not responding to demo tapes he has sent the show.

Both suspects were arrested.
