Do you think it would be bad to come out to my dad in one of these ridiculous ways?

Well I've come out to my whole family.... except my dad. Now I really am not sure how my dad will react. A part of me tells me that he already knows, but I am really not sure. I am pretty sure he is not homophobic because:
1. He ordered the movie The Kids are Alright on netflix and told us all to watch it
2. He always laughs about the morman commercials and says that the mormans are trying to get their popularity up after advocating for the anti gay law (prop 8) in California
3. When DADT was repealed, he said something like, yea this is different from when they let women fight in the war because gay people already were in the army just no one knew they were gay.
4. I don't think I have ever heard him say anything homophobic.
5. He had two gay uncles (they were partners)
So I think he will react fairly well (I am at least confident that he is not homophobic).
But the thing is, my dad is not the kind of person that has heart to heart deep conversations. He is generally a very awkward person to begin with.
So i am at a loss on how to come out to him.
Would it be bad to use one of the really silly ways to come out to him? Like spell out I'm gay on a pizza with olives, or save up your letters in scrabble untill you can spell out I am gay. Or even mentioning it nonchelantly at the dinner table, 'dad could you pass the salt to your gay daughter?' Or doing the knock knock joke, 'Knock knock. Who's there? Your daughter! Your daughter who? Is GAY!
Here is where I am getting my ideas from:
