Give your ear a yank for Carol Burnett, who turns 80 today, April 26, 2013.

Below, in a memorable episode of The Lucy Show, 34-year-old Burnett guest stars as a flight attendant trainee who is afraid of heights. Lucy is also a trainee. When the two of them take their first flight, Burnett’s character completely freaks out. I remember this from when I was a kid.

I’ve conveniently cued the video to Burnett’s freakout at the 11:18 mark. Keep watching to see Ball and Burnett sing and dance to entertain the passengers.
