Where should you put your wisdom?

Not sure if there's ever been an election where "suppositories" have been the daily talking point. But Tony Abbott is copping a lot flak for this today.

"No one, however smart, however well-educated, however experienced, is the suppository of all wisdom," said Mr Abbott on a campaign stop in Melbourne on Monday.

Cue guffaws and a bonanza of toilet humour and puerile puntastic headlines in the world's media, from "the butt of all jokes" to "Abbott gives supporters a bum steer" to "hitting a bum note". I'm sure there are a few readers who can suggest a few more.

The clip has gone viral on social media and #suppository was even trending on Twitter at one point (surely a world first). Even his supporters were left shifting awkwardly in their seats (sorry!)

It's led to unfortunate comparisons with the master of the political slip of the tongue, George W Bush.
