Mila Kunis got one. Justin Timberlake did, too. Kate Upton got hers just last week. And now, Bo Obama's got his.

The first dog has joined the growing list of celebrities who've been invited to go out in a YouTube video posted for all to see.

In the video set to the jaunty vocals of the Marvelettes' "Please Mr. Postman," Ramona the 3-year-old goldendoodle can be seen thinking about not having a date for the Oregon Humane Society's Doggie Dash May 11 in Portland.

Ramona's next thoughts - illustrated by white dialogue clouds - are inspired: "Maybe … I should invite Bo Obama!!"

The dog tries several methods to reach Bo: she has no luck on Twitter (she's shown "typing" at a computer keyboard); she tries Facebook (still no luck), and even calls him up ("What do you mean he doesn't have a cellphone?").

So she composes a letter. The handwriting was shaky and words were misspelled, but the message to the famous 4-year-old Portuguese water dog was clear: "Dear Bo, will u goz to Doggie Dash wit me? Romona."

A formal invitation across the screen later on asked the first dog to be the event's "Grand Dog Marshal … And Marry Ramona, if you like!"

The video is part of the Oregon Humane Society's campaign to get support for its 26th annual Doggie Dash, a fundraising event.

David Lytle, a spokesman for the independent nonprofit, said the invitation to the first dog was a way to "highlight shelter pets and raise their profile."

The method might be cute, but Lytle said the invitation was no joke.

"It's not just a stunt," he said, adding that the organization was working with Oregon Congressional delegations to get the invitation to the right hands in the White House. "It would be a big boon to shelter pets. (Bo) was not adopted from a shelter and the Obamas made a lot of statements (that) they wanted a shelter pet and then they got Bo as a gift, kind of out of the blue, so this is their opportunity to come out and show their support for animals that are less well off and that need a lot of loving TLC that they just don't get."

The humane society hasn't heard back from Bo, but it's holding out hope. "What could be more enticing than a wonderful pitch from a fluffy white goldendoodle," Lytle said.

The humane society has also set up a petition on Change. org to seek support for getting Bo to the event. As of Thursday night, there were 681 signatures.
