When House is playing on-line poker, he asks Taub if he should call or raise with a "double gutshot straight draw." When the poker screen is shown, House is holding 8-9, and the board is 10-A-2-7. House therefore has an open-ended straight draw (four consecutive cards, 7-8-9-10) needing either a 6 or a Jack to make the straight. A "double gut-shot straight draw" would have the same number of outs, but the gaps in the straight would be inside, rather than on the ends (e.g., holding Jack-9 against a board of 7-10-King, where an 8 or a Queen completes the straight). The odds of making the straight are the same for open-ended and for double gutshot, as for each there are exactly 8 cards that will make the straight (e.g., four 8s, four Queens), but House's identification of the hand he is holding is incorrect.
