I think its all a load of hog-wash, but I'm no lawyer...  I did a quick search on Google for "who's your daddy" and found over 778,000 hits...  Did a quick search on the same phrase at the US Copyright office and had 119 hits...  Did a longer search at the US PTO and found 23 hits on "who's your daddy?" and two hits on "who's ya daddy?"...

There are two companies claiming rights to the "who's your daddy?" phrase on shirts...  One is Who's Ya Daddy in Florida, and the other one is Who's Your Daddy in California...  The Who's Your Daddy company in California is in deep debt for the small company of no product and no revenue that they claim to be (over US$1.5M as of 2005?)...

I wonder if Toby Kieth ( got permission to use "Who's Your Daddy"...  Hmmm...  Did Lordi or Benny Benassi get permission to call their songs "Who's Your Daddy?"  Thinking about it, I wonder if the Zombies still have any claim to the phrase (year: 1969, song: Time of the Season)...

A search for "Who's Da Daddy?" had zero hits in the USPTO and US Copyright databases.
A search for "Who's The Daddy?" had zero hits in the USPTO database, and 5 hits in the US Copyright database (all were non-genealogy usages)...

You are right, going to "Who's Your Granddaddy" looses the subtlety, but it may be closer to the eternal genealogy question.  I'm not sure going to "Who's Da Daddy?" or "Who's The Daddy?" would be any better, but in my uneducated opinion, they appear to be available to use...

Can you believe there is a company called "Who's Ya
Daddy, Inc."?? I couldn't either, but here it is:

Based on that report, I wonder if they might be a
trademark troll

Nonetheless, I'm not interested in a law suit. So I
have changed the shirt to say "Who's Your
Granddaddy?". I know, it loses the subtlety, but it
should keep me from litigation.

For those of you who have already ordered the shirt,
I'm not sure what will happen to your order. Sorry for
any inconvenience.
