Liverpool took advantage of some comical Brighton defending to book their place in the last eight of the FA Cup.
A sixth round clash against Stoke City at Anfield now awaits, after the Reds punished Gus Poyet's Seagulls for three own goals on an afternoon to forget for the Championship side.
Martin Skrtel headed the hosts into an early lead, meeting Steven Gerrard's corner on five minutes to beat Peter Brezovan - the chief culprit with some poor goalkeeping throughout the match.
But the early signs looked good for the Seagulls, and they drew level 12 minutes later, when Kazenga LuaLua's long-range free-kick bear Pepe Reina in the Reds' goal.
With half-time looming, the Merseyside outfit earned a crucial advantage though. Luis Suarez's initial effort was blocked, but Glen Johnson's follow-up header went in off the unfortunate Liam Bridcutt.
Andy Carroll was rewarded for his impressive display on 57 minutes, latching onto Stewart Downing's cut-back and firing into the net to make it 3-1, before Bridcutt put past his own goalkeeper again 14 minutes later.
It got worse for Brighton though, when Lewis Dunk chested into his own net under minimal pressure to make it 5-1 with a third own goal for the visitors.
Luis Suarez had time to miss a penalty after Dirk Kuyt was brought down in the penalty box, and the Dutchman would impressive after his introduction from the bench. Suarez got his goal on 85 minutes, heading home from Carroll's nod back across goal.
A day to forget for the sorry Seagulls.
