Gumor's Orifice Confusion

Gumor said to Selma. Selma can I put my finger in your bellybutton? Selma said "No."

Gumor asked her again Selma can I put my finger in your bellybutton? Selma said "No."

Gumor asks her again Selma can I put my finger in your bellybutton? Selma says "OK."

A minute later Selma says Gumor that's not my bellybutton. Gumor says, ''Suprise, Suprise! That's not my finger either.''
