The Colm & Jim-Jim Breakfast Show was an Irish breakfast radio show, broadcast weekdays on RTÉ 2fm. The show, hosted by Colm Hayes and Jim-Jim Nugent, began broadcasting in March 2007 when the duo moved from rival station FM104.

The Colm & Jim-Jim Breakfast Show was on air from 6 am to 9 am, Mon-Fri, directly before 2fm's flagship show, The Gerry Ryan Show. It placed sixteenth in a survey of national radio listenership figures taken between June 2007 and June 2008, with 202,000 adult listeners. The show is in direct competition with The Ian Dempsey Breakfast Show which airs on Today FM, and placed 12th in the same survey. Each Saturday morning a compilation of "best bits" from the previous week was broadcast between 9 am and 10 am. The Colm & Jim-Jim Breakfast Show was Ireland's third (3rd) most popular podcast in 2007, with 601,203 downloads. In 2008, The Colm & Jim-Jim Breakfast Show's listenership figures were reduced by 5,000 to 197,000.

The move from FM104 represented a change in listenership for Hayes and Nugent as 2fm broadcasts nationally whilst FM104 reaches only listeners in Dublin.

In initial promotional material, the new breakfast show was referred to as the 2fm Alarm Clock in reference to the duo's previous show The Strawberry Alarm Clock. However, when FM104 threatened legal action the name was dropped in favour of the current moniker.

The duo's new slot led to the axing of Orla Rapple's Early Show and replaced Marty in the Morning in the 2fm breakfast slot. Since Ryan Tubridy left The Full Irish and defected to RTÉ Radio 1, the station had struggled to replace him in a difficult period which also saw the short-lived The Rick & Ruth Breakfast Show axed after six months due to declining listenership figures. Prior to this difficulties arose when 2fm's breakfast host, Ian Dempsey moved to Today FM. He now presents a rival breakfast show with the commercial station.

The Colm & Jim-Jim Breakfast Show was launched with sponsors Halifax. In 2007, The Colm and Jim-Jim Breakfast Show added 100,000 new listeners to their breakfast show. Whilst on 2fm the duo won an RTÉ Guide Award for "Favourite Radio Show", following the seven PPI Awards they earned whilst working on 104's Strawberry Alarm Clock for FM 104. Nugent spoke of the strictness that was rife at his now NEW workplace:

"You know when we left 104 they wouldn't let us take our awards with us. I had to sneak in at six in the morning, take them out of the cabinet and put them all on a table together and take a picture of them and stick it on my blog. It was up there for ages before they realised we were leaving."

By September 2008, an additional 24,000 listeners had been added.
