He also throws up on the former starship captain. When Leonard is playing D&D with him, he calls it the greatest day of his life. Shatner then tells Leonard that someday he'll meet a girl. Later when the girls are playing D&D Shatner says that he is going to go all Wrath of Khan on them. Kevin Smith has him put a dollar in the Star Trek jar. Penny is ready to attack the ogres to which Bill likes her “moxie”. Penny thinks that she loves his grandpa words.
In "The Colonization Application", Leonard and Penny cover themselves in body paint and roll around on a canvass while they have sex. Penny doesn't want the resulting painting in her apartment so they plan on giving it to Sheldon and telling him that William Shatner painted it.
