The dog barks.

[Drizzle]

I knew I read an interpretation somewhere that ruled this illegal, so I googled it.

Thanks to Nevadaref's post on the NFHS Board:

I have now found a better source of documentation for this ruling. The NFHS put it in print in the 2006-07 Basketball Preseason Guide on page 5.

"Play 1: Late in the game, A2 is inbounding the ball on the end line in his or her own frontcourt. In an effort to deceive the other team, A4 lines up near the sideline on his or her hands and knees and begins to simulate a barking dog. As the Team B players turn to look at A4, A2 throws the ball to A5 who makes an uncontested layup.
Ruling 1: The official shall stop play, wave off Team A's basket and issue an unsporting technical foul to A4. Team B will shoot two free throws and have the ball for a designated-spot throw-in at the division line opposite the table."
