This Monday, it's the battle of the "Brother from Another Mother," as SOAPnet celebrates Labor Day with a five-hour "One Tree Hill" marathon.

The marathon will highlight the relationship of half-brothers Nathan and Lucas Scott. The siblings, who were raised apart, must learn to co-exist both on and off the basketball court. See their journey from enemies, to frenemies, to friends, in five episodes airing from 12PM - 5PM (EST/PST).

Included? The very first episode of "One Tree Hill" -- back when Lucas was an outsider, Nathan and Peyton were dating, and Jamie wasn't even a glimmer in nerdy Haley's eye. Ah, how things have changed!

Tune in this Monday at 12PM for all the Scott brother hotness you can handle!

Which Scott brother are you more like, Nathan, or Lucas?
