My hubby had a terrible crush on Gates McFadden, and I had one on Wil Wheaton (who played Dr. Crusher's son, Wesley). Wheaton turned out to be a real jerk, but McFadden's just as awesome as ever!!!
Picard's first impression was correct. "No Children On My Bridge!"
One of our favorite sound bites from the show (we use it a LOT around here) was Picard's infamous "Shut Up, Wesley!" It's become almost as big with us as going to the diner to order a cup of "Earl Grey, HOT..."
I once did a skit with friends where Wesley passed out. Picard was present when Dr. Crusher revived him & shone a light into his eyes. "How many lights do you see?" she asked him. He replied "There are Four Lights," to which Picard exclaimed "Well, then- I didn't hit you hard enough!" He then gave Wesley a sharp blow to the head & he and Beverly started dancing around sick bay singing "Momma said to knock you out! I'm gonna knock you out!"
