Andy Murray is not known by many for his blossoming sense of humour, but followers of the British no.1 on Twitter will know all about his, at times successful, moments of comedy.
Some claim that the Scottish-born star cuts a miserable figure off-court in his approach and speech, something which Murray made a joke of during his BBC Sport's Personality of the Year award in 2013: "I can't help the way I talk."
However, those closer to him say he can be quite the joker. As recently as Christmas Day, Murray was laughed at for a glum-faced expression having had a picture taken with a novelty Christmas jumper but, again, many failed to detect the sarcasm in his post.
Nonetheless, he's cracked another joke to 2.83 million people who follow him.
Many figures in tennis have been worried about the level of heat that the players will be subjected to in 2015's first Grand Slam at the Australian Open. Last year many players collapsed under the strain and temperatures look set to match the numbers of 2014 again.
The Hopman Cup, an international tournament featuring the likes of Murray and Serena Williams, is taking place in Perth at the moment and the mercury hit a sweltering 44.5 degrees.
Despite the heat, Murray went online to make light of the hot situation: '44.5 degrees here in Perth today..sounds hot but I'm used to it though having grown up in Dunblane where January conditions are very similar,' he said to his fans.
Of course, the joke is that Dunblane, Murray's Scotland hometown, is actually nothing like Australia (I know it should not need explaining). In fact, the small town is currently enjoying temperatures of around 6 degrees and a lashing of rain to go with it.
I know exactly where I would rather be, there's no such thing as being too hot in my book.
For the Hopman Cup, the Perth stadium had the luxury of shutting its roof to repel the searing heat and changes have been made to the Australian Open's extreme heat policy after last year's events.
In three days of weather over 40 degrees in 2014's tournament, some players fainted with heatstroke, however the addition of another roof at the major has quelled fears slightly.
Murray will be hoping his match are cool affairs. He has never won Down Under, despite reaching the final three times, and is looking for a return to form after a less than satisfactory last season.
The Briton has been looking good in the warm-ups, he won an exhibition event last week and helped Great Britain to an opening Hopman Cup win over France after winning his singles match and mixed doubles encounter - paired with Heather Watson.
