Heck, pretty much any of the animals' revenges against Moneybags.
Bentley's in particular gives us this exchange:
Bentley: (After bashing Moneybags several times) One more, perhaps?
Spyro: At least!
The epilogue you get for getting all the skill points. Special mention to the game of "Whack a Bentley", which shows a mole going after Bentley with his own club, and the seals inventing "squid-boarding".
After you pay off Moneybags to rescue Agent 9, he remarks "You ever seen a bear dance?" He then chases Moneybags around, firing lasers at him. It's funnier than it sounds.
