Ted connects the hairy babies to Pat, believing him to be fooling around with the housewives on Craggy Island during his rounds.
On his rounds, Dougal is oblivious to the housewives having prepared themselves for Pat's arrival, including one that answers the door topless while another is fully naked.
Ted then receives a call from Pat, who, in revenge for losing his job, has planted a bomb on Dougal's milk float, which is set to arm if it exceeds 4 miles per hour and detonate if the speed drops below that.
Meanwhile, as Mrs. Doyle packs away her Pat Mustard memorabilia (including a giant spanner that he left with her after being unable to carry it on the milk float), Ted takes out the rubbish and sees an object in the sky.
[1] This led to the idea of having the previous milkman fired for being promiscuous with the housewives and having Ted try to figure out the mystery of the hairy babies.
Linehan had generally ruled that they should not show Ted and the others doing their roles as clergy, but felt that having the Mass being performed at this point was "too good an opportunity to pass up".
The episode was voted the best ever by the show's fans in the Channel 4 Father Ted Night, which screened on 1 January 2011 to celebrate the 15th anniversary of the programme.
