Famed Star Trek actor George Takei — Mr. Sulu — is weighing in on the hubbub around Wildrose Leader Danielle Smith's hubcap bustier.

"A campaign bus in Canada. Nice hubba hubba caps!" he posted on his Facebook page late Tuesday night, under a picture of Smith's campaign bus.

On Monday, sharp-eyed viewers saw what looked like a bustier on Smith's chest, on the side of the bus.

The new, contracted graphic design left two wheels positioned squarely at the level of Smith's chest in what appeared to be a sort of hubcap bustier.

Responses to Takei's Facebook post flooded in from Alberta and beyond. It snagged 15,475 likes; 3,436 shares and 1,970 comments by late Tuesday morning.

Ali Dotinga wrote, "Oh god. This is in my city. Lots of jokes around town but you know you've made a huge #fail when it ends up viral on Takei's facebook .... lol."

Several commenters joked about innies and outies and flat tires.

Donna Miller MacGregor wrote, "should be spinners!!"

The puns played out all day Monday, too.

Even Smith poked wry and good-natured fun at the gaffe on wheels:

"Glad to see everyone is so interested in our bus. ;) Guess we'll have to make a couple of changes huh?" she said on Twitter.
