You pull out a bunch of very colourful socks from a laundry hamper explaining to the audience that it’s hard to choose which ones to wear on a daily basis…from your exciting collection!
You hand out 8 single and different socks to 8 audience members to hold.
Ask each of them to drape their sock over either one of your arms, anywhere they like, as long as it’s not on top of anyone else’s socks.
One random audience member is selected to eliminate the socks from either arm. They make their choice and the socks from that arm are dropped into the hamper. Another audience member chooses to eliminate the odd or even socks. Whatever they select you remove and drop those socks into the hamper. Down to the last two socks you ask a final participant to choose one, they do…
You say it’s an EXACT MATCH! Lifting your trouser leg…to reveal your bare ankle! (to audience laughter!)
You then lift your other trouser leg to reveal…the MATCHING SOCK!
