Football: Hoops pray it won't be three defeats in row; SCOTTISH CUP.
A stunning Parkhead win seven years ago ranks amongst the greatest upsets in the history of the cup and ended John Barnes' disastrous reign at Celtic Park.
Inverness then followed that up three years later with a 1-0 win at home.
If Caley could pull off another victory, it would be the first time Celtic have lost a hat-trick of successive Scottish Cup games to the same club since Rangers beat them in the 2002 final.
Caley have never beaten the SPL champions in the league but Charlie Christie's side seemto hold an Indian sign over Celtic in the Cup.
Here's a reminder of the victories that have earned the Highlander's their hoodoo over the Hoops.
