Robert Pattinson's fan base breaks through barriers and generations! He seems to make an impression on everyone he meets. Just ask John Stamos! The actor spent some time with R-Pattz at his Full House co-star Bob Saget's birthday party over the weekend in L.A.!

Rob made such an impression on John that he Tweeted about it:

Can anyone be cooler than Uncle Jesse? That is a tough call, but how about the hair? Who do you think has a better mane?
