Thing is, if true this is a confirm. I watch the show sometimes and they are all EXTREMELY talented liars (kinda the point) but some stories are true. If this one is it does mean Susie is ticklish.
For UK viewers the full episode should be available on BBC iPlayer now where she will reveal whether it was a true story or not. I will check it out next time I have a spare 30mins to watch it
Susie confirmed its true, and in it she says her dad would tickle fight with her and she absolutely hated it. I like Susie, shes a well educated person on Countdown.
