Try an American Flag. Its a nice layered shooter thats red, white (clear),
and blue. The webtender version calls for Grenadine, White creme de cacao,
and blue curacao. I like to substitute peach schnapps for the white creme de
cacao. Equal parts layered Grenadine, creme de cacao, then blue curacao. Buy
crappy brands of liqueurs because no one will know the difference. For 75+
people, you're going to need about a gallon of each liqueur (maybe more) and a
whole lot of grenadine. With three gallons, you can make 384 one ounce shots
which is about 5 shots a person.
