It would be strange to see the loveable, funny Chandler Bing inside the TARDIS but I think the assistants life would suit him well. There wouldnt be anything too long term for this commitment-phobe he could even escape the Doctor if he hid deep enough within the TARDIS. Hes quite clever or at least he appears to be doing a job that seems to pay quite well, even if his friends arent quite sure of what it is. So, hed be able to work out what was going on quickly in order to help. Also, being married to the control-freak Monica has got him used to the assistant status; hed easily take orders and the Doctor wouldnt need to worry about him defying them, unless there was a chance for a joke. But the main reason that Chandler would be a brilliant companion is his sense of humour. Through ten series of Friends, he never failed to make us laugh. Wed love to hear him use his timeless sarcastic comments and witty comebacks to fend off aliens. With Chandler in the TARDIS: could it BE any funnier?
