SINGAPORE - Paralympians Theresa Goh and Yip Pin Xiu are not only good at winning medals, they are great comedians as well.

The good friends demonstrated their camaraderie in a video of themselves sharing puns at a supermarket.

Goh, 29, uploaded the video on her Facebook page on Friday (Nov 25) with this introduction: "So this was what happened when Yip Pin Xiu and I found a 24-hour supermarket last night. We were on a rollllllll~ #enjoy #lameathletes #literally #oneteamsg btw: 'oil' in Chinese sounds like 'you'."

Here's a selection:

Goh, holding a carton of Ceres fruit juice: "You're going back to school right? It's time to get Ceres (serious), Ceres, Ceres-ly."

Yip, holding Nu brand drink, then Snapple: "Nooooo... I'm getting mad I may Snapple at you."

Goh: "You know when you're in a dog park or garden... you have to be careful where you walk..."

Yip: "I don't walk."

Goh: "Aiyah, if you walk...in case you Kickapoo."

They ended the video by singing "All I want for Christmas is you" in an aisle filled with cooking oil. As Goh explained, the Chinese word for "oil" sounds like "you".

Both were giggling uncontrollably by then at their own jokes.

Watch the video for more puns from the Wheaties, I mean witty, duo.

At the Rio Olympics, Yip won two golds (50m backstroke S2, 100m backstroke S2) and Goh returned home with a bronze (100m breaststroke SB4).
