BIG Brother twin tricks are nothing new for Rockhampton twins Melissa and Stacey Mitchell.
From confusing their boyfriends to standing behind each other's birthday cakes, the pair have been masterminds of mistaken identity.
Top-rating TV show Big Brother has introduced double trouble in the house by throwing in identical twins Greg and David (their madeup name Logan).
The twins are swapped regularly and have three minutes to fill the other in on what's been going on.
Melissa said it was not until they reached high school that she and her sister started having twice as much fun tricking classmates and family members.
"One day we decided to play up a bit and so Stacey put her arms around my boyfriend,'' Melissa said.
"He didn't notice until he turned around and almost kissed her that it wasn't me.' ' Stacey said she and Melissa would often swap beds and go along with conversations with people who could not tell the difference between them.
"Because Melissa, mum and I sound all the same on the phone, we would often play tricks on those on the other end of the line before handing the phone over to who the call was for,'' she said.
"Everyone gets tricked. You never get sick of it.''
Melissa interrupted: "I get sick of being called Stacey.'' Being twins had its advantages, Melissa said.
They would often dress similarly by coincidence and sometimes spoke in unison.
But looking alike does not necessarily mean being alike for these 20-year-olds.
"I am definitely the evil one, so I am told,'' Melissa laughed.
"I seem to act up a lot more and get in to trouble whereas Stacey, who is 12 minutes older than me, is more conservative and mature.
