You can't be serious, right?
While I think whoever did this was genius to freeze these frames, the Hangover and this episode are still very different.
The shot at the craps table has Ned saying because of Deuteronomy 7 he can't gamble, Homer picks number 7 and they win.
Homer and Ned both get married. The women they marry are evil, not nice.
The White Lion is from the Sigfried and Roy show they go to, not in their hotel room.
Dredrick Tatum was preventing Homer and Ned from dishonoring their marriage in Vegas, not because they stole his tiger.
While I'm sure the writers of the Hangover have been inspired by this episode, they aren't the same and aren't remotely a ripoff.
