There once was a man named Michael Finnegan, He grew whiskers on his chinnegan, Shaved them off and they grew back innegan, Poor old Michael Finnegan. (Beginnegan).
Here it is with chords and a key change:

Forty years on an iceberg [triangular "iceberg" shape], over the ocean wide [wavy motion]. Nothing to wear but jammys [slide hands up and down the sides of your body], nothing to do but slide ["slide" motion]. Woo! The air was cold and icy [shiver!] the frost began to bite [nipping motion]. I had to hug a polar bear [hug yourself or neighbor] to keep me warm at night. Oh!
Repeat over and over, but on the second repeat, hum the first line; on the third repeat, hum the first and second lines, and so on. "Woo!" and "Oh!" are always sung. On the very last repeat, sing all the words.
This song has more drama than tune, but should be sung rather dryly.
Three [hold up 3 fingers] chartreuse buzzards [hunch shoulders, look mean] Sitting in a dead tree [arms out like gnarled branches, head off to side] OH look [shade eyes with hand] One has flown A-way [point to distance] What A shame [one hand at forehead in dramatic gesture] Darn.
Two chartreuse buzzards .... One chartreuse buzzard ....
No chartreuse buzzards [hunch shoulders, look mean] Sitting in a dead tree [arms out like gnarled branches, head off to side] OH, look [shade eyes with hand] One has RE-turned [beckoning motion] Let us RE-joice [arms up in joy] Yay.
One chartreuse buzzard .... Two chartreuse buzzards ....
Three chartreuse buzzards [hunch shoulders, look mean] Sitting in a dead tree [arms out like gnarled branches, head off to side] Now they're ALL here [arms spread] This is THE end ["end" motion] Yay.
