In the past, he acted as Phoebe Buffay's boyfriend on Friends. At that time, Jennifer had broken her toe and was using a Segway to get around the set.
He told this during Graham Norton Show, "I was on the set for my first episode and Jennifer was on a Segway because she had broken her toe, and everyone was marvelling at it".
"Matt LeBlanc asked to have a go and immediately knew how to do it. I then asked to try it too. I spun round and rolled it right over Jennifer's foot!
"The producers look of panic was if to say, 'Is it too late to fire him? Has his character been established yet?' I felt awful. Such an inauspicious start."
