I don't like the fact that Penny's dad love immediatly Leonard, because he is the most intelligent (ex) boyfriend of her. What would he do, if he meet Sheldon first? XD He is more genius. And I miss Shenny moment, like in the first season...

I'm looking forward for Leonard and Penny stuff. Sheldon already has a very nice girlfriend. Go the Shammy. LOL

It looks like a funny episode, but truth be told I was disappointed when I found out Penny and Leonard kiss, (even if it's for a lie). I think it would have been so much better if Penny had asked Sheldon to lie to her father; we could've laughed so much! Sheldon and Penny have the best scenes - add to that a kiss and it would've become one of the best episodes
