Quote from Marshall in Who Wants To Be A Godparent

[fantasy scene of tracksuit-wearing Barney on an airplane with tracksuit-wearing fourteen-year-old Marvin:] Barney: You're gonna love Amsterdam, little bro. [Barney and Marvin put on their sleep masks and recline their chairs] [reality:] Marshall: Okay, Barney's out of this round.
