The Big Bang Theory/The IT Crowd crossovers?

[skaredykat]

I rarely leave the one corner of fandom I no-longer-quite-lurk in, but a conversation made two of us wonder about/long for:
Are there any The IT Crowd/The Big Bang Theory crossovers? Ideally with a Sheldon/Moss pairing or friendship? AO3 and the yuletide archive seem to say no :( so if you know of any, thank you!
