Post-match interviews can sometimes be hard-work or even dull.
Across sport, athletes tend to tow the line, not wanting to upset anyone and keep focus on their upcoming battles.
However, at this year's Australian Open that has not always been the case.
As you can see in the video above, some of the stars in Melbourne have rather enjoyed their time on the mic after their matches.
And it has caused much enjoyment for the fans too and in this collection a certain Venus Williams truly steals the show.
The incredible American sisters, Serena and Venus Williams, will face each other in Saturday’s Australian Open showpiece, having last contested a slam final at Wimbledon in 2009.
Seldom has sport seen two siblings achieve such success and here, we look at some of the staggering numbers behind the sisters’ dynasty.
Who do you think will win Saturday’s final?
44 – Saturday’s match will be the 44th grand slam final the pair have contested either together or against another player. It will be Serena’s 29th and Venus’ 15th.
22 – Serena’s current total of grand slam wins. She sits tied with Steffi Graf as the second-most decorated player of all-time. Margaret Court leads the way with 24, but 23 for Serena would be the best in the Open era.
7 – Slams won by Venus, the last being Wimbledon in 2008 when she beat Serena in two sets. Since then, struggles with Sjogren’s syndrome – an autoimmune disease – have slowed her down.
9 – Saturday will be the ninth meeting between them in slam finals, Serena leads that rivalry 6-2.
71 – Their combined aged – Venus is 36 and Serena 35 – make this the oldest women’s grand slam in the Open era, with Venus the oldest Australian finalist.
27 – Total career meetings, with Serena ahead 16-11.
13 – Slams won together in doubles.
120 – Career singles titles, with Serena winning 71 and Venus 49.
92 – Million pounds of career earnings, Serena with £65m and Venus £27m.
Wawrinka forced a decider from two sets down on Rod Laver Arena but Federer held his nerve to win 7-5 6-3 1-6 4-6 6-3 and advance to his 28th major final.
It means Federer, at 35, is the oldest man to reach a grand slam final since the 39-year-old Ken Rosewall made it to the last hurdle at the US Open in 1974.
He will now face either his old foe Rafael Nadal or the resurgent Grigor Dimitrov, who play in the other semi-final on Friday.
"I couldn't be happier right now," Federer said on court afterwards.
"Everything happened so quickly, I had to check the score after the match was over, I was like, 'is it all real?'
