XD I don't know about the movie... Although it could be very random and with the potential of funny of course...
I was just thinking of the most classic episodes. Ironically most of them feature Ross and I always thought of him as my least favourite. Is my subconcious trying to tell me something?!
But my favorite moments were as mention - Ross' Sandwich. I can totally relate ^~
The one with Ross' Teeth. Haha that one is too good... How white can you make your teeth... seriously xD.
Umm, The one with the Fake Tan. Yes. Again Ross xD. I just love the part where Chandler goes "You could be a one man play for Ebony and Ivory!". It's not a direct quote... but it's something like that anyway ^_^

Me thinks I have a secret Ross obsession... I always do go for the geek O_O
