In another strip, Dilbert met Antina, an overly masculine female coworker who caused his tie to flatten and point downward, strengthening the idea of the tie being a phallic symbol (Adams himself has said that he does not know what it means). On January 11, 2011, Dilbert was diagnosed with pon farr which caused an irresistible urge to mate. His tie was straight for the next two strips. Sometimes when Dilbert is surprised, scared, or has been beaten up, his tie goes straight. In the strip published October 13, 2014, Dilbert announced to Dogbert that his company had a new dress code, "Business Dorky". Dilbert's white shirt and striped tie were replaced with a red polo shirt and a badge on a lanyard. Subsequent strips published Monday through Saturday show all of the company employees wearing this same outfit, with the polo shirts varying in color between blue, green, yellow, red, orange, and purple. The Sunday strips continued to show the characters in their original outfits, until November 9, 2014. In a story arc spanning from September 17, 1990 to October 9, 1990, Dilbert is killed by a wild deer and Mother Nature (although he is seen alive in an unrelated September 23, 1990 strip), but is cloned back to life by the garbage man on October 5, 1990. Dilbert also momentarily dies twice in the TV series episode "The Shroud of Wally".
