Choose from a list of obscure but achievable Guinness World Records (examples below).

• Most T-shirts worn at once (current record is 260+)
• Most socks put on one foot in 30 seconds
• Most sticky notes stuck to face in 60 seconds
• Fastest time to arrange alphabet soup into alphabetical order
• Most spoons balanced on the body
• Most eggs held in one hand
• Most marshmallows eaten in one minute (no hands!)
• Most balloons popped with the butt in 30 seconds

(yes, these are all real)

Practice makes perfect - practice your record attempt to unlock that muscle memory.

Attempt it live in front of league-mates, stream viewers, or strangers at the park, the Loser must go all-in trying to beat the record.

Track It properly: Must follow the official guidelines of Guinness (if going for actual certification) or do a faithful re-creation if going unofficial.
