denial, despite showing symptoms, but agrees to take a pregnancy test with Sharon. When Berg finds out from a news report that a glow-in-the-dark condom he used was defective he thinks Irene could be pregnant. Not wanting to worry her, he tries to get a urine sample from her without telling her. Pete is still annoyed at Ashley for giving up on their relationship to go to Stanford. Four different endings were filmed for viewers to decide whether one of the three central female characters (Sharon, Ashley, or Irene) should become pregnant or whether none should be. The plan was to have the pregnant one (which ultimately ended up being Ashley) give birth at the end of the proposed fifth season.

Ratings The show had strong ratings success during its run, peaking in season 2 with an average of 12.0 million viewers. The series premiere, titled "The Pilot", was watched by 17.94 million viewers, airing after The Drew Carey Show. The episode got a 15.61 Nielsen rating and won its 18-49 adult demographic. It was ABC's biggest opening since Spin City. The eleventh episode of season 1, "Two Guys, a Girl and How They Met", got a 6.7 Nielsen rating, a big drop from the series premiere. The estimated number of viewers was 7.69 million. The show continued to have success during the first few seasons but never reached the high rating of "The Pilot". Its key adult 18–49 audience was predominantly female (55%). It was ranked #1 in its time period with Total Viewers, outperforming Beverly Hills, 90210, The Nanny, and Dawson's Creek. It was also #1 in its time slot with key adults 18–49 and with all male demographics. It was the #3 sitcom on ABC with key adults 18–34.
