From the various series in between:

• "Ménage à Troi" (TNG S3E24)
• "A Fistful of Datas" (TNG S6E8)
• "The Magnificent Ferengi" (DS9 S6E10)
• "Take Me out to the Holosuite" (DS9 S7E4)
• "Bride Of Chaotica!" (VOY S5E12)
• "Babel One" (ENT S4E12)

Several I've omitted throughout, not counting the low hanging fruit of LD, but clearly Trek as a whole is steeped in plenty of silly episodes.
