Nesmith's last contractual Monkees commitment was a commercial for Kool-Aid and Nerf balls, in April 1970 (fittingly, the spot ends with Nesmith frowning and saying, "Enerf's enerf!"). With the band's fortunes continuing to fall, Nesmith asked to be released from his contract, and had to pay a default: "I had three years left... at $150,000 a year", which he had to pay back. He continued to feel the financial bite for years afterward until his inheritance from his mother's Liquid Paper fortune in 1980 eased those concerns.
