How big? Well, he claims to have written some fan fiction with himself in Ross's role.
So, when Jennifer Aniston visited Jimmy Kimmel Live! Wednesday night to discuss her new movie Life of Crime, he confessed his secret to her – and enlisted her help in making his fantasy come true.
But wait, folks, there's more: Courteney Cox and Lisa Kudrow showed up, too.
Because Kimmel's playing "Ross," naturally, most of the jokes revolve around Ross's sexual prowess. For example, when Cox shows up as Monica, her opening line is, "Hey Ross, everyone down at Central Perk is talking about how good you are at making love," and Kudrow enters with, "Hey, are you guys talking about how good Ross is at making love without me?" (According to Kimmel's script, Joey and Chandler are both dead – and for a very good reason.)
Sadly, Cox has put rumors of a Friends reunion to bed – so far, the odd dinner seems to be the closest the cast has gotten to officially reuniting, at least until Kimmel made this happen. Check out the full clip below.
