I’m at the age now where just putting my cigar in its holder is a thrill.

Burns, famous for his cigar and for joking about longevity, uses a mild double entendre to turn aging into comedy. The line suggests that in old age even small, routine actions can feel exciting—either because life’s pleasures narrow to modest comforts or because the body’s limitations make ordinary tasks newly charged with sensation. The humor depends on understatement and self-mockery: he presents a tiny act as a “thrill,” inviting the audience to laugh while also recognizing a truth about getting older. It fits Burns’s public persona of genial, unembarrassed candor about age and desire.
