The Sharks, established in 1967, have never won a premiership having lost their four previous grand final appearances. The club first made a grand final in 1973, going down to Manly 10-7. Cronulla lost to Manly once again in 1978 when a grand final replay was needed after the first grand final ended 11-11. Manly won the rematch 16-0 three days later with the final being played on a Tuesday. The Sharks only other grand final was the 1997 Super League final where they lost 26-8 to Brisbane.
The Warriors and the Titans are the only other NRL sides yet to claim their maiden premiership titles.
At least the Sharks have been to the final in recent times, unlike the Western Bulldogs.
Saturday's AFL grand final against the Sydney Swans will be the Bulldogs first shot at a premiership since 1961. Saturday's opponents the Swans have won four premierships since 2005.
The Bulldogs have fallen one game short of the grand final five times since 1997, including three straight seasons 2008-2010.
This year is the 92nd season for the Bulldogs, formally known as Footscray. 92 seasons just one title, which came in 1954.
It's the longest title drought in the AFL. The Melbourne Demons last won a title in 1964 while St Kilda's only premiership came in 1966.
If the Sharks and Bulldogs both win next weekend, it could be a good omen for the Chicago Cubs. The Cubs have the longest active title drought in American sports having last won baseball's World Series in 1908. The Cubs became the first side the clinch a spot in the playoffs earlier this month.
