LOS ANGELES (Zap2it.com) - David Hyde Pierce's television
marriage to Daphne (Jane Leeves) on NBC's "Frasier" has
almost become a real thing for fans.

Pierce, who plays Niles, the brother of Kelsey Grammer's
Frasier Crane, says people usually talk to him at the
supermarket, congratulating him on his well-matched union.

According to the AP, Pierce says that people often tell him,
"I'm so glad you're married, she's so nice, are you going to have
kids?"

However, since it took the characters nine years to get
together, it isn't very likely for them to have a baby anytime
soon. The show, which airs Tuesdays at 9 p.m. ET, is currently
in its tenth season.

Besides playing Frasier's stuck-up and competitive psychiatrist
brother, Pierce also does the voice of Doctor Doppler in the new
animated movie "Treasure Planet."

While it would be kind of amusing to see pompous Niles become a doting daddy, adding a baby would really be the end of it all for the show.
I hope they forget the pregnancy storyline for now.

I agree with you TJL, pregnancies can kill a sitcom.

They'll probably save it until they've run out of ideas...although it could be funny...
