OK, so I thought I'd followed your advice and give "the Big bang theory" a chance.
Sorry guys, not nearly as funny "how I met your mother". Please, please get the DVD or something, you will thank me afterwards.
Anyway, I wanted to mention "The new adventures of Old Christine" as the 2nd funniest sitcom on TV right now! (after "mother" of course). It made my husband laugh so, I rest my case :-)
