After goalkeeper Richard Kingson marked his 32nd birthday last Sunday with a fine display in the Black Stars' opening 1-0 win over Serbia, it was the turn on Tuesday of defender John Pantsil, who was 29.
In a typically flamboyant display of African joy, the squad partied with hotel staff, enjoyed a cake, a jug of beer and a food fight, before coach Milovan Rajevac ensured normal concentration was resumed.
He knows Ghana have an excellent chance to be Africa's most successful side here and could at least emulate Cameroon (1990) and Senegal (2002) in reaching the quarter-finals.
"For Australia, this is the last chance," he said. "They are a very competitive nation and I am sure they will fight. Their performance against Germany did not show the real picture."
The 2001 vintage reached the world youth cup final while the current crop won the under 20's trophy in Egypt in 2009.
Australia's Dutch coach Pim Verbeek has had to fight fires and rebuild morale this week. He may bring in Harry Kewell, who has recovered from a long-term injury, to replace Cahill and may also select Mark Bresciano and Josh Kennedy, who are also fit.
Kewell, 31, arguably Australia's finest player, if not as effective as Cahill, has rejected talk of rifts and rallied the team.
"It wasn't a great effort against Germany, but there are two games to go and anything can happen in a World Cup," he said.
"We were all disappointed in that game, but we are all men and we take it on the chin. There are still two games to go and we have got time to turn things around."
