David Lee Jaco (born January 24, 1954) is a retired heavyweight boxer.
He spent his career as a journeyman, fighting boxers to build up their career records.
He retired in 1994 with 24 wins (19 by knockout), 25 losses (18 by knockout), and 1 draw.
Although he lost bouts to Mike Tyson, George Foreman, Tommy Morrison, Carl Williams, Tony Tucker, Buster Douglas, Mike Weaver and Oliver McCall, he won bouts against the undefeated Donovan Ruddock, Rick "King Kong" Keller, and many more.
Jaco was once profiled on ABC's Prime Time Live as a "Palooka", or someone who never refused a fight for the money.
Jaco later said, "I was a palooka, one of those guys who basically goes in there looking for a big payday.
I made thousands when I fought, but I didn't consider myself a palooka.
