Dilbert walks by a workman standing on a chair and nailing a sign to the wall. The sign says, "10 Injury Free Days." Dilbert hears, "Bam! Aaaeeii!! R-r-roll thud." Dilbert stands over the workman who has fallen off the chair. Dilbert says, "This is very ironic." The workman says, "No, it was ironic when it happened eleven days ago."
