How Do Ducks Float?

One afternoon while Jaime and I were driving back to school from the mall...

Tracy: It amazes me how can ducks float.

[contemplative silence]

Jaime: How DO ducks float?

Tracy: *shrug* I don't know. Just a random thought.

It was that same thought that led Jaime on a quest to find an answer and he kept asking me over and over until finally another afternoon 2 months later on a trip back from jamba juice...

Jaime: Tracy, guess what I found the answer to why ducks can float.

Tracy: Huh? Wait a minute. Oh my god you're still wondering about that?

Jaime: I know but I had to get Elvia to look it up.

Tracy: Okay, did you find the answer? How DO ducks float then?

Jaime: Alright, so basically there's like this special gland that produces oil back near the duck's tail and as the duck grooms itself, the oil is spread out over its feathers and coats them making them waterproof. HOWEVER, if you were to put a degreaser on the duck, it would remove the oil and the duck would drown in water! Therefore, making that Dawn commercial where they use the dishwashing liquid to clean the duck that was caught in the oil spill, cruelty to animals!!!

Tracy: ...

Tracy: But that commercial was so cute...

Jaime: Isn't that sad though??!!

Tracy: Well, I'm sure they let the duck re-oil itself before they tossed it back into the wild, if it has the ability to do that?
