the big bang theory has often had sci fi actors and actresses appear on the show for example summer glau,katee sackoff,george takei and will wheaton. i think it's time someone from stargate got on there and who better than amanda tapping epecially when you consider not only was she on stargate sg1 for ten years but she is also currently the main character on sanctuary and she appeared frequently on the stargate spin offs. with so many sci fi appearances sheldon,leonard,raj and howard would easily recognise her if they met her at a convention or on a plane. i feel it would also be a great opportunity for the big bang theory to make more sci fi humour that are not about the more obvious shows like star trek and doctor who. so if you agree with me that it would be great to see amanda tapping on the big bang theory as herself then sign here.
