This episode tickled me infinitely much. (Gulp). Aaron did an excellent job under the circumstances, and managed to make an hour-long Star Trek soliloquy alternately interesting, funny, and moving (especially towards the end with the Tig-slingshotting-around-the-sun bit). And it's a testament to the chemistry and comedic strength of the entire PB family that just imagining Tig, David, and Kyle's reactions to Aaron at various points throughout the episode made me laugh.
Trailing off now...
