Tommy - who also hosts the Carrie and Tommy radio show for the Hit Network with Carrie Bickmore - is known for teasing his cohosts with his funny antics.
In June, he left Lisa Wilkinson red-faced on The Project after enlightening her of a dirty joke.
Tommy - who joined the show via satellite from London - was seen riding around the city naked on a bike.
When Lisa didn't understand what a passer-by meant by saying, "He's a grower, not a shower," the comedian cheekily supplied her with an explanation:
"I think it means I've got a small c**k, Lisa."
The 59-year-old was mortified by her own gaffe and covered her face on live TV.
"How good's live TV? I know Tommy Little well, why did I do that? Next time, stop me before I kill again," she told her fellow co-hosts when she regaining her composure.

In an exclusive interview with Who last year, the radio host said he thinks laughter is "sexy."
"I think that laughing is sexy. I love to laugh. But for attention ... I really want people to laugh at my jokes, so yes I find that sexy."
