I have a big DAD mug that middle girl LT gave me about 5 years ago and I always have my cup of milky coffee in it first thing when I get up -without fail every day. I also have a battered one largest girl LT made me about 12 years ago at a pottery place and an old worlds greatest dad one that i would never throw. Oh and a Met Office one I have had for about 15 years. 
so yes
