Wasn't it 'dormouse' for the 737? I recall the following story:
The early Boeing 737s were short and dumpy and somehow gained the nickname of "the Dormouse".
Heathrow Ground :
"Speedbird 345, Taxy via the inner to hold Bravo, and if you can get past the Lufthansa Dormouse already at Bravo, you are number 1 for departure"
"Roger, taxy via the inner to Bravo, number 1 in front of the Lufthansa Dormouse, Speedbird 345".
"Ground this is Lufthansa 800"
"Lufthansa 800 go ahead"
"We wish you to know that Lufthansa 800 is a Boeing 737 200 of Lufthansa, the national airline of Germany - and we do not wish to be referred to as a Dormouse"
"Lufthansa 800..... Roger".
A little while later -
"Lufthansa 800, Ground - after the departing Speedbird line up and wait runway 28 Right. After departure, SQUEAK 2366, your departure frequency will be 119.725 - contact tower now on 118.5"
Silence came the reply .......
