Fee-hee-hee-heeneh!
The catchphrase of the character Eric from Boy Meets World as he addresses poor old Mr Feeney. Eric also once made a customized doll that played this phrase when you pulled its string.
Eric: Feeney? Is that you?
Mr. Feeney: Maybe if I'm quiet he'll go away.
Eric: Feeney! Fee-hee-hee-heeneh! Dog!
Mr. Feeney: Maybe if I'm quiet he'll go away.
Eric: Feeney! Fee-hee-hee-heeneh! Dog!
