After over 15 years together it was only a matter of time.
The lads finally came to blows today, after Dave used Dermot's favorite mug that is strictly off limits!
This resulted in the pair having it out in the Today FM car park, where things got quite heated and bloody.
Have a look at how the events panned out below.
Will Dermot seek revenge? Will Dave get found out? What happened to the mug?
Tune into Dermot and Dave, weekday mornings from 9am to find out!
