Perfect Strangers (1986)

S6E11 Sunshine Boys

Larry's old high school adversary, Bunky McDermott, pays him a visit with an enticing offer: an invitation to an exclusive dinner party and a chance to join his elite social club. Thrilled by the prospect, Larry fabricates a story about a trip to the Caribbean to impress Bunky. To back up his tall tale, Larry and Balki decide to hit the tanning bed, but their plan backfires spectacularly, leaving them both with painful sunburns instead of a golden glow.
